METHOD AND A REAGENT MIXTURE FOR REMOVING METAL IONS FROM AN AQUEOUS SOLUTION BY MEANS OF LIQUID-LIQUID EXTRACTION

摘要

Abstract: A liquid-liquid extraction processis disclosed, in which an aqueoussolution, containing metal ions, iscontacted with an organic liquidsubstantially insoluble water.The organic liquid contains twowater-insoluble reagents, viz. adiester of dithiophosphoric acidand an organic phosphate, in a pre-ferred volume ratio of between 1:10and 2:1. The organic liquid mayalso contain a diluent for thereagents.
