摘要
A carbon disulphide-isoamyl alcohol-pyridine ternary solvent was found to be applicable to the extraction of transition metal ions such as Zn2+, Co2+, Ni2+ Cd2+ and Cu2+, but not Mn2+, Fe3+, CrO42- and MoO42-. The ions were extracted as isoamylxanthates from aqueous sulphate medium. The optimum extraction conditions, such as mixing ratio of solvents, pH and shaking time for equilibrium, and the extraction mechanism were established.
