The extractability of divalent cations was evaluated as a function of relationship between distribution ratio of the metal and pH or ligand concentration. The highest extraction percentage of Cu2+ and Ni2+ showed pH 7.0 and 6.4. It was concluded that the ligand can effectively be used in solvent extraction of copper(II) and nickel(II) from the aqueous phase to the organic phase.eninfo:eu-repo/semantics/closedAccessThio Schiff BaseTransition Metal ComplexesExtractionElectrochemical StudiesSpectroscopic and electrochemical studies of transition metal complexes with N,N?-bis(2-aminothiophenol)-1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane and structure effects on extractability of ligand towards some divalent cationsSpectroscopic and electrochemical studies of transition metal complexes with N,N?-bis(2-aminothiophenol)-1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane and structure effects on extractability of ligand towards some divalent cationsArticle1381211991209WOS:0002512384000012-s2.0-3674907982610.1007/s00706-007-0713-3Q2Q3
