摘要：
The application of the new extractant Cyanex 302 (Cyanamid), bis (2,4,4-trimethylpentyl) monothiophosphinic acid, as an extraction agent of zinc(II) from sulphate medium is studied. The extraction system is studied as a function of several variables, such as the diluent of the organic phase, temperature, metal concentration in the aqueous phase, etc., along with the zinc(II) stripping stage by sulphuric acid. The behaviour of Cyanex 302 has been studied with respect to other organophosphorous extractants and also the selectivity of the reagent in the system zinc(II) versus iron(III).
