Abstract
Tris(2-ethylhexyl)phosphate is proposed as an extractant for the solve nt extraction of zinc and copper salicylate. The optimum extraction co nditions are established by studying the various experimental paramete rs such as pH, sodium salicylate concentration, tris(2-ethylhexyl)phos phate concentration, equilibration period, and various diluents. The p robable extracted species as ascertained by log D-log C plots is Zn(HS al)(2)2T2EHP and Cu(HSal)(2)2T2EHP. The method permits mutual separati on of zinc and copper and can be used for separation and determination of zinc and copper in environmental and pharmaceutical samples.
