摘要：

The extraction of Cd(II) from chloride media of 1.0 M ionic strength by the commercial extractant Cyanex 302 in kerosene has been studied over a range of pH and reagent concentrations. The data have been analyzed both graphically and numerically to determine the stoichiometry of the extracted complexes and their extraction constants. The species CdR(2)(HR) and CdR(2)(HR)(2), HR being the active component in the commercial extractant, bis (2,4,4-trimethylpentyl)thiophosphinic acid, have been found to be responsible for the extraction behaviour observed.
