Abstract
To research possible use of sulfonamide-type polyanionic chelators having ethylene bridges as extractants, extraction (cation-exchange) behavior of Cu2+ with several chelators was investigated. Tripod sulfonamide-type chelator, tris [2- (p-toluenesulfonamido) ethyl] amine, showed higher extractability than its monosulfonamide analog, 2- (p-toluenesulfonamido) ethylamine. Although the former can be generally considered as trianionic tetradentate chelator, on extraction of Cu2+, it acted as dianionic tridentate ligand and formed neutral 1: 1 complex having one coordinating H2O. The formed complex seems to be stabilized by chelate effect of the ligand and shielding effect of the coordinating sulfonamido group.
