| Abstract: | The paper studied that the sulphuric acid solution contained zinc and nickel were separated by solvent extraction using D2EHPA as extraction agent.The results showed that ,in the best conditions,the extraction and back-extraction ratio of zinc reached 99.34% and 99.79%, respectively. The extraction and back-extraction ratio of nickel reached 99.16% and 99.58%, respectively.The separation factor of zinc and nickel was more than 25 000.The content of Zn and Ni in the back-extraction solution respectively conform the electrolysis requirements. |
