摘要：

Separation of copper(II) and platinum(IV) in extraction from binary acid chloride solutions with liquid membranes containing technical-grade di(2-ethylhexyl)phosphoric acid with addition of tri-n-octyl amine in 1,2-dichloroethane under the conditions of the galvanostatic electrodialysis was studied. The influence exerted by the current density and composition of aqueous solutions and liquid membranes on the rate and selectivity of copper(II) extraction was analyzed. The optimal conditions of metal separation were determined.
