Beer's law is obeyed in the range of 3.3-26.0 µg (0.13-1.04 ppm) of Kelthane per 25ml of final solution. The molar absorptivity and Sandell's sensitivity were found to be 4.32 × 10 5 L•mol-1 •cm-1 and 0.022 µg•cm-2 respectively. The method is found to be free from interferences of other organochlorine pesticides and various co-pollutants and can be successfully applied for the determination of kelthane in environmental samples.","owner":{"id":215226724,"first_name":"Etesh","middle_initials":null,"last_name":"Janghel","page_name":"EteshJanghel","domain_name":"independent","created_at":"2022-02-19T09:42:48.670-08:00","display_name":"Etesh Janghel","url":"https://independent.academia.edu/EteshJanghel"},"attachments":[{"id":91766994,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/91766994/thumbnails/1.jpg","file_name":"AJAC20110600007_77880290.pdf","download_url":"https://www.academia.edu/attachments/91766994/download_file?st=MTczMzk1NTA5OSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Spectrophotometric_Determination_of_Kelt.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/91766994/AJAC20110600007_77880290-libre.pdf?1664524001=\u0026response-content-disposition=attachment%3B+filename%3DSpectrophotometric_Determination_of_Kelt.pdf\u0026Expires=1733958699\u0026Signature=HVGgZX~T0BguNiHNOathamJ9vNZZgJmAzAiP6G7HH8nKAa--GgcPMV~1NlVnKagqeZHTP5K5-P-DV4yIwbbbyuqcpjIBmBQTvBKL25GAhMm3Oomj19~jllOfJezMkwHPIP5H2IVfraMZEmUK3EEcF1LUwoLy-JeHrlARWONqT5wsub7U~4xs59kix6~VBL2YFGd95OVRFHLJDKIrCG~2JUXUD4YFQm70ZaER1di7GViAIueffxUXtl~RiuZy2h9o0FPmtsQoo6gD~zmUalRLK62gxYE3-fMRPquWZOYKzdLvtHQfQ-ScWthz3dtauoN-MVshihI~QlY-9l4zodfktQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":523,"name":"Chemistry","url":"https://www.academia.edu/Documents/in/Chemistry"},{"id":15374,"name":"HPLC-MS of environmental samples","url":"https://www.academia.edu/Documents/in/HPLC-MS_of_environmental_samples"},{"id":178351,"name":"Spectrophotometry","url":"https://www.academia.edu/Documents/in/Spectrophotometry"},{"id":358483,"name":"Acaricide","url":"https://www.academia.edu/Documents/in/Acaricide"},{"id":1608017,"name":"Benzidine","url":"https://www.academia.edu/Documents/in/Benzidine"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="87602758"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/87602758/Heat_gradient_analytical_technique_for_the_simultaneous_determination_of_some_aromatic_amines"><img alt="Research paper thumbnail of Heat-gradient analytical technique for the simultaneous determination of some aromatic amines" class="work-thumbnail" src="https://attachments.academia-assets.com/91766997/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/87602758/Heat_gradient_analytical_technique_for_the_simultaneous_determination_of_some_aromatic_amines">Heat-gradient analytical technique for the simultaneous determination of some aromatic amines</a></div><div class="wp-workCard_item"><span>Journal of Analytical Chemistry</span><span>, 2008</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A new and sensitive analytical technique has been developed for the simultaneous determination of...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A new and sensitive analytical technique has been developed for the simultaneous determination of six aromatic amines (aniline, p-nitroaniline, m-nitroaniline, o-nitroaniline, 1,3 phenylenediamine and 1, 4 phenylenediamine).

It is based on the differential migration of coloured derivatives formed by the reaction of diazotized amines with orcinol on a silica gel plate. Quantitative evaluation of amine is made by visual comparison of intensities of colour by spectrophtotometry.

The method is based on alkaline hydrolysis of Fly-Fighter to dichloroacetaldehyde followed by benzoic acid in alkaline medium. The absorption maxima of the reddish-brown dye formed is measured at 510 nm. Beer’s law is obeyed over the concentration range of 2.3 to 25 µg in a final volume of 25 ml (0.092-1.00 ppm). The molar absorptivity, Sandell’s sensitivity and correlation coefficient were found to be 1.8x10 4 l mole -1 cm -1 , 0.002 µg cm -2 and 09989 respectively. The lower limit of detection is about 0.001. The standard deviation and relative standard deviation were found to be ± 0.002 and 1.98% respectively. The method is simple sensitive and free from interferences of other pesticides and diverse ions. Other organophosphorous pesticides do not interfere with the proposed method.
