Effects of structural changes of new organophosphorus cationic exchangers on a solvent extraction of cobalt, nickel and manganese from acidic chloride media

Abstract

The effects of structural changes of organophosphorus cationic exchangers on metal-distribution curves (extraction efficiency<italic>vs.</italic>pH) have been investigated for the recovery of cobalt(<sc>ii</sc>), nickel(<sc>ii</sc>) and manganese(<sc>ii</sc>) from acidic chloride solutions.
