class="card-text"><strong>Abstract:</strong></p> A new chelating resin is prepared by coupling Amberlite XAD-4 with 1-amino-2-naphthole through an azo spacer. The resulting sorbent has been characterized by FT-IR, elemental analysis and thermogravimetric analysis (TGA) and studied for preconcentrating of Cu (II) using flame atomic absorption spectrometry (FAAS) for metal monitoring. The optimum pH value for sorption of the copper ions was 6.5. The resin was subjected to evaluation through batch binding of mentioned metal ion. Quantitative desorption occurs instantaneously with 0.5 M HNO3. The sorption capacity was found 4.8 mmol.g-1 of resin for Cu (II) in the aqueous solution. The chelating resin can be reused for 10 cycles of sorption-desorption without any significant change in sorption capacity. A recovery of 99% was obtained the metal ions with 0.5 M HNO3 as eluting agent. The method was applied for metal ions determination from industrial waste water sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Amberlite%20XAD-4%3B%20Copper%20%28II%29%3B%20Flame%20atomicabsorption%3B%20Chelator%3B%201-amino-2-%20naphthole" title="Amberlite XAD-4; Copper (II); Flame atomicabsorption; Chelator; 1-amino-2- naphthole">Amberlite XAD-4; Copper (II); Flame atomicabsorption; Chelator; 1-amino-2- naphthole</a> </p> <a href="https://publications.waset.org/5292/amberlite-xad-4-functionalized-with-1-amino-2-naphthole-for-determination-and-preconcentration-of-copper-ii-in-aqueous-solution-by-flame-atomic-absorption-spectrometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5292/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5292/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5292/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5292/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5292/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5292/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5292/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5292/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5292/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5292/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5292.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">2408</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Determination and Preconcentration of Iron (II) in Aqueous Solution with Amberlite XAD-4 Functionalized with 1-amino-2-naphthole by Flame Atomic Absorption Spectrometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Homayon%20Ahmad%20Panahi">Homayon Ahmad Panahi</a>, <a href="https://publications.waset.org/search?q=Mahshid%20Nikpour%20Nezhati"> Mahshid Nikpour Nezhati</a>, <a href="https://publications.waset.org/search?q=Faranak%20Mahmoudi"> Faranak Mahmoudi</a>, <a href="https://publications.waset.org/search?q=Elham%20Moniri"> Elham Moniri</a>, <a href="https://publications.waset.org/search?q=Meghdad%20Karimi"> Meghdad Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>A new chelating resin is prepared by coupling Amberlite XAD-4 with 1-amino-2-naphthole through an azo spacer.
