摘要

The synergistic effect of Cyanex 302 on solvent extraction of nickel and cadmium from sulfate solution with D2EHPA diluted in kerosene was investigated with the aim of increasing separation efficiency. Experiments were carried out within a pH range of 0.1-5.0 using sole D2EHPA and D2EHPA-Cyanex 302 mixtures in different ratios. Increasing Cyanex 302 to D2EHPA ratios in the organic phase caused a left shifting of the extraction isotherm of cadmium and a right shifting of the extraction isotherm of nickel. As a result, optimum separation was found with a Cyanex 302 to D2EHPA ratio of 0.1M:0.5M. In the present system, effect of a modifying reagent such as TBP was studied. The influence of various diluents including kerosene and carbon tetrachloride was also investigated.
