The extractability of divalent cations was evaluated as a function of relationship between distribution ratios of the metal and pH or ligand concentration. The highest extraction percentage of Cu+2 and Ni+2 were at pH 7.0 and 6.4, respectively. The ligand can effectively be used in solvent extraction of copper(II) and nickel(II) from aqueous phase to organic phase.eninfo:eu-repo/semantics/closedAccessSpectroscopic StudiesExtraction StudiesThio Schiff BaseSpectroscopic and extraction studies of new transition metal complexes with N,N'-bis(2-aminothiophenol)-1, 4-bis(2-carboxaldehydephenoxy)butaneSpectroscopic and extraction studies of new transition metal complexes with N,N'-bis(2-aminothiophenol)-1, 4-bis(2-carboxaldehydephenoxy)butaneArticle61711461156WOS:0002551582000152-s2.0-4244912758110.1080/00958970701502334Q3Q3
