Thus, finding a safe alternative solvent will have a strong and positive impact on environments and general health of the world population. d-limonene from the orange peel was extracted through a steam distillation procedure followed by a deterpenation process and combining this achievement by using it as a solvent for extracting lycopene from tomato fruit as a substitute of dichloromethane. Lycopene content of fresh tomatoes was determined by high-performance liquid chromatography after extraction. Yields obtained for both extractions showed that yields of d-limonene’s extracts were almost equivalent to those obtained using dichloromethane. The proposed approach using a green solvent to perform extraction is useful and can be considered as a nice alternative to conventional petroleum solvent where toxicity for both operator and environment is reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20solvent" title="alternative solvent">alternative solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=d-limonene" title=" d-limonene"> d-limonene</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=lycopene" title=" lycopene"> lycopene</a> </p> <a href="https://publications.waset.org/abstracts/51267/first-approach-on-lycopene-extraction-using-limonene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2482</span> Solvent Extraction in Ionic Liquids: Structuration and Aggregation Effects on Extraction Mechanisms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandrine%20Dourdain">Sandrine Dourdain</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Lopez"> Cesar Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamir%20Sukhbaatar"> Tamir Sukhbaatar</a>, <a href="https://publications.waset.org/abstracts/search?q=Guilhem%20Arrachart"> Guilhem Arrachart</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephane%20Pellet-Rostaing"> Stephane Pellet-Rostaing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A promising challenge in solvent extraction is to replace the conventional organic solvents, with ionic liquids (IL). Depending on the extraction systems, these new solvents show better efficiency than the conventional ones. Although some assumptions based on ions exchanges have been proposed in the literature, these properties are not predictable because the involved mechanisms are still poorly understood. It is well established that the mechanisms underlying solvent extraction processes are based not only on the molecular chelation of the extractant molecules but also on their ability to form supra-molecular aggregates due to their amphiphilic nature. It is therefore essential to evaluate how IL affects the aggregation properties of the extractant molecules. Our aim is to evaluate the influence of IL structure and polarity on solvent extraction mechanisms, by looking at the aggregation of the extractant molecules in IL. We compare extractant systems that are well characterized in common solvents and show thanks to SAXS and SANS measurements, that in the absence of IL ion exchange mechanisms, extraction properties are related to aggregation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction%20in%20Ionic%20liquid" title="solvent extraction in Ionic liquid">solvent extraction in Ionic liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregation" title=" aggregation"> aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=Ionic%20liquids%20structure" title=" Ionic liquids structure"> Ionic liquids structure</a>, <a href="https://publications.waset.org/abstracts/search?q=SAXS" title=" SAXS"> SAXS</a>, <a href="https://publications.waset.org/abstracts/search?q=SANS" title=" SANS"> SANS</a> </p> <a href="https://publications.waset.org/abstracts/107612/solvent-extraction-in-ionic-liquids-structuration-and-aggregation-effects-on-extraction-mechanisms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2481</span> Application of Deep Eutectic Solvent in the Extraction of Ferulic Acid from Palm Pressed Fibre</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ng%20Mei%20Han">Ng Mei Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Nu%27man%20Abdul%20Hadi"> Nu'man Abdul Hadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extraction of ferulic acid from palm pressed fiber using deep eutectic solvent (DES) of choline chloride-acetic acid (ChCl-AA) and choline chloride-citric acid (ChCl-CA) are reported. Influence of water content in DES on the extraction efficiency was investigated. ChCl-AA and ChCl-CA experienced a drop in viscosity from 9.678 to 1.429 and 22.658 ± 1.655 mm2/s, respectively as the water content in the DES increased from 0 to 50 wt% which contributed to higher extraction efficiency for the ferulic acid. Between 41,155 ± 940 mg/kg ferulic acid was obtained after 6 h reflux when ChCl-AA with 30 wt% water was used for the extraction compared to 30,940 ± 621 mg/kg when neat ChCl-AA was used. Although viscosity of the DES could be improved with the addition of water, there is a threshold where the DES could tolerate the presence of water without changing its solvent behavior. The optimum condition for extraction of ferulic acid from palm pressed fiber was heating for 6 h with DES containing 30 wt% water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20eutectic%20solvent" title="deep eutectic solvent">deep eutectic solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ferulic%20acid" title=" ferulic acid"> ferulic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20fibre" title=" palm fibre"> palm fibre</a> </p> <a href="https://publications.waset.org/abstracts/165450/application-of-deep-eutectic-solvent-in-the-extraction-of-ferulic-acid-from-palm-pressed-fibre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2480</span> Solvent extraction of molybdenum (VI) with two organophosphorus reagents TBP and D2EHPA under microwave irradiations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Boucherit">Ahmed Boucherit</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Khalaf"> Hussein Khalaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Paredes"> Eduardo Paredes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Todol%C3%AD"> José Luis Todolí</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solvent extraction studies of molybdenum (VI) with two organophosphorus reagents namely TBP and D2EHPA have been carried out from aqueous acidic solutions of HCl, H2SO4 and H3PO4 under microwave irradiations.

In this study pilot scale supercritical carbon dioxide (SCCO₂) extraction was used to produce decaffeinated black tea in place of solvent extraction. Pressure (250, 375, 500 bar), extraction time (60, 180, 300 min), temperature (55, 62.5, 70 °C), CO₂ flow rate (1, 2 ,3 LPM) and co-solvent quantity (0, 2.5, 5 %mol) were selected as extraction parameters. The five factors BoxBehnken experimental design with three center points was performed to generate 46 different processing conditions for caffeine removal from black tea samples. As a result of these 46 experiments caffeine content of black tea samples were reduced from 2.16 % to 0 – 1.81 %. The experiments showed that extraction time, pressure, CO₂ flow rate and co-solvent quantity had great impact on decaffeination yield. Response surface methodology (RSM) was used to optimize the parameters of the supercritical carbon dioxide extraction. Optimum extraction parameters obtained of decaffeinated black tea were as follows: extraction temperature of 62,5 °C, extraction pressure of 375 bar, CO₂ flow rate of 3 LPM, extraction time of 176.5 min and co-solvent quantity of 5 %mol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercritical%20carbon%20dioxide" title="supercritical carbon dioxide">supercritical carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=decaffeination" title=" decaffeination"> decaffeination</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20tea" title=" black tea"> black tea</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a> </p> <a href="https://publications.waset.org/abstracts/58747/determinaton-of-processing-parameters-of-decaffeinated-black-tea-by-using-pilot-scale-supercritical-co2-extraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2478</span> Hydrometallurgical Treatment of Abu Ghalaga Ilmenite Ore</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20A.%20Ibrahim">I.

Iron content in the produced liquor is separated by solvent extraction using TBP as a solvent. All parameters affecting the efficiency of the dissolution process were separately studied including the acid concentration, solid/liquid ratio which controls the ilmenite/acid molar ratio, temperature, time and grain size. The optimum conditions at which maximum leaching occur are 30% HCl acid with a solid/liquid ratio of 1/30 at 80 °C for 4 h using ore ground to -350 mesh size. At the same time, all parameters affecting on solvent extraction and stripping of iron content from the produced liquor were studied. Results show that the best extraction is at solvent/solution 1/1 by shaking at 240 RPM for 45 minutes at 30 °C whereas best striping of iron at H₂O/solvent 2/1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ilmenite%20ore" title="ilmenite ore">ilmenite ore</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20solvent%20extraction" title=" titanium solvent extraction"> titanium solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu%20Ghalaga%20ilmenite%20ore" title=" Abu Ghalaga ilmenite ore"> Abu Ghalaga ilmenite ore</a> </p> <a href="https://publications.waset.org/abstracts/76625/hydrometallurgical-treatment-of-abu-ghalaga-ilmenite-ore" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76625.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2477</span> Microwave Accelerated Simultaneous Distillation –Extraction: Preparative Recovery of Volatiles from Food Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Mohamed">Ferhat Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukhatem%20Mohamed%20Nadjib"> Boukhatem Mohamed Nadjib</a>, <a href="https://publications.waset.org/abstracts/search?q=Chemat%20Farid"> Chemat Farid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Simultaneous distillation–extraction (SDE) is routinely used by analysts for sample preparation prior to gas chromatography analysis. In this work, a new process design and operation for microwave assisted simultaneous distillation – solvent extraction (MW-SDE) of volatile compounds was developed. Using the proposed method, isolation, extraction and concentration of volatile compounds can be carried out in a single step. To demonstrate its feasibility, MW-SDE was compared with the conventional technique, Simultaneous distillation–extraction (SDE), for gas chromatography-mass spectrometry (GC-MS) analysis of volatile compounds in a fresh orange juice and a dry spice “carvi seeds”. SDE method required long time (3 h) to isolate the volatile compounds, and large amount of organic solvent (200 mL of hexane) for further extraction, while MW-SDE needed little time (only 30 min) to prepare sample, and less amount of organic solvent (10 mL of hexane). These results show that MW-SDE–GC-MS is a simple, rapid and solvent-less method for determination of volatile compounds from aromatic plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=essential%20oil" title="essential oil">essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=distillation" title=" distillation"> distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=carvi%20seeds" title=" carvi seeds"> carvi seeds</a> </p> <a href="https://publications.waset.org/abstracts/30977/microwave-accelerated-simultaneous-distillation-extraction-preparative-recovery-of-volatiles-from-food-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30977.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">560</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2476</span> Analytical Study of Cobalt(II) and Nickel(II) Extraction with Salicylidene O-, M-, and P-Toluidine in Chloroform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sana%20Almi">Sana Almi</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Barkat"> Djamel Barkat </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The solvent extraction of cobalt (II) and nickel (II) from aqueous sulfate solutions were investigated with the analytical methods of slope analysis using salicylidene aniline and the three isomeric o-, m- and p-salicylidene toluidine diluted with chloroform at 25°C.

Hideaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Degradative solvent extraction is the method developed for biomass upgrading by dewatering and fractionation of biomass under the mild condition. However, the conversion mechanism of the degradative solvent extraction method has not been fully understood so far. The rice straw was treated in 1-methylnaphthalene (1-MN) at a different solvent-treatment temperature varied from 250 to 350 <sup>o</sup>C with the residence time for 60 min. The liquid membrane-Fourier Transform Infrared Spectroscopy (FTIR) technique is applied to study the processing mechanism in-depth without separation of the solvent. It has been found that the strength of the oxygen-hydrogen stretching (3600-3100 cm<sup>-1</sup>) decreased slightly with increasing temperature in the range of 300-350 <sup>o</sup>C. The decrease of the hydroxyl group in the solvent soluble suggested dehydration reaction taking place between 300 and 350 <sup>o</sup>C. FTIR spectra in the carbonyl stretching region (1800-1600 cm<sup>-1</sup>) revealed the presence of esters groups, carboxylic acid and ketonic groups in the solvent-soluble of biomass. The carboxylic acid increased in the range of 200 to 250<sup> o</sup>C and then decreased. The prevailing of aromatic groups showed that the aromatization took place during extraction at above 250 <sup>o</sup>C. From 300 to 350 <sup>o</sup>C, the carbonyl functional groups in the solvent-soluble noticeably decreased. The removal of the carboxylic acid and the decrease of esters into the form of carbon dioxide indicated that the decarboxylation reaction occurred during the extraction process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20waste" title="biomass waste">biomass waste</a>, <a href="https://publications.waset.org/abstracts/search?q=degradative%20solvent%20extraction" title=" degradative solvent extraction"> degradative solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanism" title=" mechanism"> mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=upgrading" title=" upgrading"> upgrading</a> </p> <a href="https://publications.waset.org/abstracts/79176/the-mechanism-study-of-degradative-solvent-extraction-of-biomass-by-liquid-membrane-fourier-transform-infrared-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79176.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2474</span> Extraction of Essential Oil From Orange Peels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aayush%20Bhisikar">Aayush Bhisikar</a>, <a href="https://publications.waset.org/abstracts/search?q=Neha%20Rajas"> Neha Rajas</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditya%20Bhingare"> Aditya Bhingare</a>, <a href="https://publications.waset.org/abstracts/search?q=Samarth%20Bhandare"> Samarth Bhandare</a>, <a href="https://publications.waset.org/abstracts/search?q=Amruta%20Amrurkar"> Amruta Amrurkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orange peels are currently thrown away as garbage in India after orange fruits' edible components are consumed.

Butein, a natural colorant, has many medicinal properties apart from its use in dyeing industries. Extraction of butein from the flowers of flame of forest was carried out using ultrasonication bath. Solid loading (2-6 g), extraction time (30-50 min), volume of solvent (30-50 mL) and types of solvent (methanol, ethanol and water) have been studied to maximize the yield of butein using the Taguchi method. The highest yield of butein 4.67% (w/w) was obtained using 4 g of plant material, 40 min of extraction time and 30 mL volume of methanol as a solvent. The present method provided a greater reduction in extraction time compared to the conventional method of extraction. Hence, the outcome of the present investigation could further be utilized to develop the method at a higher scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=butein" title="butein">butein</a>, <a href="https://publications.waset.org/abstracts/search?q=flowers%20of%20Flame%20of%20the%20Forest" title=" flowers of Flame of the Forest"> flowers of Flame of the Forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20bath" title=" ultrasonic bath"> ultrasonic bath</a> </p> <a href="https://publications.waset.org/abstracts/79692/extraction-of-natural-colorant-from-the-flowers-of-flame-of-forest-using-ultrasound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79692.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">475</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2471</span> The Solvent Extraction of Uranium, Plutonium and Thorium from Aqueous Solution by 1-Hydroxyhexadecylidene-1,1-Diphosphonic Acid </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Bouhoun%20Ali">M.

The HHDPA was previously synthesized and characterized by FT-IR, 1H NMR, 31P NMR spectroscopy and elemental analysis. The effects contact time, initial pH, initial metal concentration, aqueous/organic phase ratio, extractant concentration and temperature on the extraction process have been studied. An empirical modelling was performed by using a 25 full factorial design, and regression equation for extraction metals was determined from the data. The conventional log-log analysis of the extraction data reveals that ratios of extractant to extracted U(VI), Pu(IV) and Th(IV) are 1:1, 1:2 and 1:2, respectively. Thermodynamic parameters showed that the extraction process was exothermic heat and spontaneous. The obtained optimal parameters were applied to real efﬂuents containing uranium(VI), plutonium(IV) and thorium(IV) ions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title="solvent extraction">solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a>, <a href="https://publications.waset.org/abstracts/search?q=plutonium" title=" plutonium"> plutonium</a>, <a href="https://publications.waset.org/abstracts/search?q=thorium" title=" thorium"> thorium</a>, <a href="https://publications.waset.org/abstracts/search?q=1-hydroxyhexadecylidene-1-1-diphosphonic%20acid" title=" 1-hydroxyhexadecylidene-1-1-diphosphonic acid"> 1-hydroxyhexadecylidene-1-1-diphosphonic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/37851/the-solvent-extraction-of-uranium-plutonium-and-thorium-from-aqueous-solution-by-1-hydroxyhexadecylidene-11-diphosphonic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37851.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2470</span> Supercritical CO2 Extraction of Cymbopogon martini Essential Oil and Comparison of Its Composition with Traditionally Extracted Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aarti%20Singh">Aarti Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anees%20Ahmad"> Anees Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Essential oil was extracted from lemon grass (Cymbopogon martini) with supercritical carbondioxide (SC-CO2) at pressure of 140 bar and temperature of 55 °C and CO2 flow rate of 8 gmin-1, and its composition and yield were compared with other conventional extraction methods of oil, HD (Hydrodistillation), SE (Solvent Extraction), UAE (Ultrasound Assisted Extraction). SC-CO2 extraction is a green and sustainable extraction technique. Each oil was analysed by GC-MS, the major constituents were neral (44%), Z-citral (43%), geranial (27%), caryophyllene (4.6%) and linalool (1%). The essential oil of lemon grass is valued for its neral and citral concentration. The oil obtained by supercritical carbon-dioxide extraction contained maximum concentration of neral (55.05%) whereas ultrasonication extracted oil contained minimum content (5.24%) and it was absent in solvent extracted oil.

The results showed that antioxidant activity of the Deverra scoparia essential oil was more effective as compared to ascorbic acid and trolox. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deverra%20scoparia" title="Deverra scoparia">Deverra scoparia</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20assisted%20extraction" title=" ultrasound assisted extraction"> ultrasound assisted extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolic%20content" title=" total phenolic content"> total phenolic content</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a> </p> <a href="https://publications.waset.org/abstracts/25874/optimization-of-extraction-conditions-for-phenolic-compounds-from-deverra-scoparia-coss-and-dur" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">595</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2467</span> Ultrasound Assisted Extraction and Microwave Assisted Extraction of Carotenoids from Melon Shells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Brinda%20Lakshmi">A.

The use of a magnetic organic liquid (also known as ferrofluid), consisting of magnetite nanoparticles coated by oleic acid dispersed in the organic diluent, has proven successful to speed up phase disengagement. The method, however, has never been used industrially; therefore, the aim of this study is to raise its main limitations. Tests were carried out using a ferrofluid containing 30 g/l of magnetite dissolved in commercial aliphatic kerosene Exxsol D80. The efficiency of cobalt extraction ([Co] = 1 g/l) with 10% v/v Cyanex 272 (bis-2,4,4-trimethylpentyl phosphinic acid) at changing pH of the aqueous phase (2 to 7) was found unaffected in the conditions studied. However, the chemical resistance of the ferrofluid in contact with deionized water at changing acidity (from 10-7 to 2 mol/l) revealed that the nanoparticles are not resistant when contacted to aqueous solutions with a pH ≤ 2. Such result represents a serious limitation to the applicability of the method mainly to hydrometallurgical systems because solvent extraction operations are normally done in acid conditions, therefore more effective strategies to coat the particles are required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20solvent%20extraction" title="magnetic solvent extraction">magnetic solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=oleic%20acid" title=" oleic acid"> oleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetite%20nanoparticles" title=" magnetite nanoparticles"> magnetite nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanex%20272" title=" cyanex 272"> cyanex 272</a> </p> <a href="https://publications.waset.org/abstracts/41603/magnetic-solvent-extraction-using-nanoparticles-coated-by-oleic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41603.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2464</span> Synergistic Extraction of Cobalt (II) from Sulfate Medium by Mixtures of Capric Acid and Methyl Isobutyl Cétone in Chloroform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Adjel">F.

The solvent power and selectivity can be further increased by using surfactant as additive which facilitate phase separation and to increase raffinate yield. The aromatics in lube oil were extracted at different temperatures (ranging from 333.15 to 343.15K) and different concentration of surfactant (ranging from 0.01 to 0.1% wt).The extraction temperature and the amount of sulfate lauryl éther de sodium In phenoll were investigated systematically in order to determine their optimum values. The amounts of aromatic, parafﬁnic and naphthenic compounds were determined using ASTM standards by measuring refractive index (RI), viscosity, molecular weight and sulfur content. It was found that using 0,01%wt. surfactant at 343.15K yields the optimum extraction conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=lubricating%20oil" title=" lubricating oil"> lubricating oil</a>, <a href="https://publications.waset.org/abstracts/search?q=aromatics" title=" aromatics"> aromatics</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbons" title=" hydrocarbons"> hydrocarbons</a> </p> <a href="https://publications.waset.org/abstracts/19800/extraction-of-aromatic-hydrocarbons-from-lub-oil-using-sursurfactant-as-additive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19800.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">521</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2462</span> Synergistic Extraction Study of Nickel (II) from Sulfate Medium by Mixtures of Capric Acid and Tri-N-Octylphosphine Oxide in Chloroform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Adjel">F.

Luckay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the growing popularity of electric vehicles and the importance of cobalt as part of the cathode material for lithium-ion batteries, demand for this metal is on the rise. Recycling of the cathode materials by means of solvent extraction is an attractive means of recovering cobalt and easing the pressure on limited natural resources. In this study, a series of straight chain and macrocyclic diamine ligands were developed for the selective recovery of cobalt from the solution containing nickel and manganese by means of solvent extraction. This combination of metals is the major cathode material used in electric vehicle batteries. The ligands can be protonated and function as ion-pairing ligands targeting the anionic [CoCl₄]²⁻, a species which is not observed for Ni or Mn. Selectivity for Co was found to be good at very high chloride concentrations and low pH. Longer chains or larger macrocycles were found to enhance selectivity, and linear chains on the amide side groups also resulted in greater selectivity over the branched groups. The cation of the chloride salt used for adjusting chloride concentrations seems to play a major role in extraction through salting-out effects. The ligands developed in this study show good selectivity for Co over Ni and Mn but require very high chloride concentrations to function. This research does, however, open the door for further investigations into using diamines as solvent extraction ligands for the recovery of cobalt from spent lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrometallurgy" title="hydrometallurgy">hydrometallurgy</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title=" solvent extraction"> solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=cobalt" title=" cobalt"> cobalt</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20batteries" title=" lithium-ion batteries"> lithium-ion batteries</a> </p> <a href="https://publications.waset.org/abstracts/178956/selective-solvent-extraction-of-co-from-ni-and-mn-through-outer-sphere-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178956.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2460</span> Solvent Extraction and Spectrophotometric Determination of Palladium(II) Using P-Methylphenyl Thiourea as a Complexing Agent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shashikant%20R.%20Kuchekar">Shashikant R.

The process is based on simultaneous heating of sample matrix and extracting solvent under microwave energy. Methanol was used as the extracting solvent, which has excellent berberine solubilizing power and warms up under microwave attributable to its great dispersal factor. Extraction conditions like time of irradition, microwave power, solute-solvent ratio and temperature were optimized using Taguchi design and berberine was quantified using high performance thin layer chromatography. The ranked optimized parameters were microwave power (rank 1), irradiation time (rank 2) and temperature (rank 3). This kind of extraction mechanism under dual heating provided choice of extraction parameters for better precision and higher yield with significant reduction in extraction time under optimum extraction conditions. This developed extraction protocol will lead to extract higher amounts of berberine which is a major anti-diabetic moiety in Tinospora cordifolia which can lead to development of cheaper formulations of the plant Tinospora cordifolia and can help in rapid prevention of diabetes in the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=berberine" title="berberine">berberine</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave" title=" microwave"> microwave</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi" title=" Taguchi"> Taguchi</a> </p> <a href="https://publications.waset.org/abstracts/58304/optimizing-microwave-assisted-extraction-of-anti-diabetic-plant-tinospora-cordifolia-used-in-ayush-system-for-estimation-of-berberine-using-taguchi-l-9-orthogonal-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58304.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2458</span> Oil Extraction from Sunflower Seed Using Green Solvent 2-Methyltetrahydrofuran and Isoamyl Alcohol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergio%20S.%20De%20Jesus">Sergio S.

The results showed that using classic method with methanol and chloroform presented the extraction oil yield with the values of 31-44% (w/w) and values of 36-45% (w/w) using green solvents for extractions. Among the two extraction methods, 2 methyltetrahydrofuran and isoamyl alcohol ratio 2:1 provided the best results (45% w/w), while the classic method using chloroform and methanol with ratio of 3:1 presented a extraction oil yield of 44% (w/w). It was concluded that the proposed extraction method using 2-methyltetrahydrofuran and isoamyl alcohol in this work allowed the same efficiency level as chloroform and methanol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20solvent" title=" green solvent"> green solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane" title=" sugarcane"> sugarcane</a> </p> <a href="https://publications.waset.org/abstracts/52653/oil-extraction-from-sunflower-seed-using-green-solvent-2-methyltetrahydrofuran-and-isoamyl-alcohol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2457</span> Selective Solvent Extraction of Calcium and Magnesium from Concentrate Nickel Solutions Using Mixtures of Cyanex 272 and D2EHPA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20S.%20Guimar%C3%A3es">Alexandre S.

Mansur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of organophosphorus extractants Cyanex 272 and D2EHPA on the purification of concentrate nickel sulfate solutions was evaluated. Batch scale tests were carried out at pH range of 2 to 7 using a laboratory solution simulating concentrate nickel liquors as those typically obtained when sulfate intermediates from nickel laterite are re-leached and treated for the selective removal of cobalt, zinc, manganese and copper with Cyanex 272 ([Ca] = 0.57 g/L, [Mg] = 3.2 g/L, and [Ni] = 88 g/L). The increase on the concentration of D2EHPA favored the calcium extraction. The extraction of magnesium is dependent on the pH and of ratio of extractants D2EHPA and Cyanex 272 in the organic phase. The composition of the investigated organic phase did not affect nickel extraction. The number of stages is dependent on the magnesium extraction. The most favorable operating condition to selectively remove calcium and magnesium was determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solvent%20extraction" title="solvent extraction">solvent extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=organophosphorus%20extractants" title=" organophosphorus extractants"> organophosphorus extractants</a>, <a href="https://publications.waset.org/abstracts/search?q=alkaline%20earth%20metals" title=" alkaline earth metals"> alkaline earth metals</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a> </p> <a href="https://publications.waset.org/abstracts/41602/selective-solvent-extraction-of-calcium-and-magnesium-from-concentrate-nickel-solutions-using-mixtures-of-cyanex-272-and-d2ehpa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41602.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2456</span> Chemical Composition of the Essential Oil of Citrus aurantium Isolated by Solvent Free Microwave Assisted Extraction and Hydrodistillation Extraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masume%20Rezaie">Masume Rezaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20H.%20Farjam"> Mohammad H.

Thus, the sources of metal ions come from the metal manufacturing industry, fertilizers, batteries, paints, pigments and so on. Solvent extraction of metal ions has given an important role in the development of metal purification processes such as the synergistic extraction of some divalent cations metals ( M²⁺), the ions metals from various sources. This work consists of a water purification technique that involves the lead and copper systems: Pb²⁺, H₃O+, Cl⁻ and Cu²⁺, H₃O⁺, Cl⁻ for diluted solutions by a mixture of tri-n-octylphosphine oxide (TOPO) or Tri-n-butylphosphate(TBP) and di (2-ethyl hexyl) phosphoric acid (HDEHP) dissolved in kerosene. The study of the fundamental parameters influencing the extraction synergism: cation exchange/extraction solvent have been examined. <p class="card-text"><strong>Keywords:</strong> <a
