EXTRACTION OF IONS OF Zn AND Cd FROM THIOCYANATE SOLUTIONS BY MELTS OF MIXTURES OF DIANTIPIRILMETHANE AND BENZOIC ACID

The extraction of ions of Zn and Cd from acid thiocyanate solutions by melts of mixtures of diantipirilmethane and benzoic acid is studied. Optimal conditions of delamination and formation of liquids as well as extractions of metal ions are determined. The possibility of the quantitative extraction of ions of Zn and Cd from thiocyanate solutions by diantipirilalcanes is presented. The composition of extractable complex compounds is set and the mechanism of extraction is offered.
