Özet
Triethylammonium 2-(diphenylphosphinoamino)-5-methylbenzenesulfonate (2) has been synthesized by treating Ph2PCl with 4-aminotoluene-3-sulfonic acid. The new compound was characterized by IR, H-1- and P-31-NMR, and elemental analysis. Liquid-liquid extraction of Ni (II) ions using synthesized aminophosphine derivative as new extractants was studied. The influence of critical parameters on the extraction properties of aminophosphine derivative such as solution pH and ligand mass were investigated. The liquid-liquid extraction ability of newly synthesized compound has also been compared another aminophosphine derivative (1). UV-vis spectrophotometry used to determine the liquid/liquid extraction efficiencies of Ni (II) metal ions at various conditions. Both of the extractant was found to be efficient for extraction of Ni (II) metal ions with recoveries of 84.8 and 81.5% for ligands 1 and 2 respectively.
