Abstract
The extraction of Zn(II) from 1.0 M KCl by Cyanex 302 dissolved in toluene was studied as a function of the total extractant concentration, the equilibrium pH and the total metal concentration. Experimental data, treated both graphically, using curve-fitting analysis, and numerically, by the computer program letagrop-distr, can be explained by assuming the extraction of the species ZnClR (HR), ZnR 2 (HR) 2, ZnL 2 and ZnL 2(HL)(HR) 3, where (HR) stands for bis(2,4,4-trimethylpentyl)monothiophosphinic acid, the active component of Cyanex 302, and (HL) represents bis(2,4,4-trimethylpentyl)dithiophosphinic acid, the active component of Cyanex 301 extractant, which is present in commercial Cyanex 302 as a minor component.
