摘要：本文简要介绍了皂化P204微乳液膜体系萃取钴镍的反应机理，研究了萃原液初始浓度，外水相pH、P204 浓度、萃取时间和相比对钴镍分离系数的影响，从而确定钴镍离子分离的最优操作条件：萃原液pH为2.0,相比 V (o):V (a)为 2: 1时 ,单级萃取10min,萃原液初始浓度为0.5mol/L,10 %P204和90 %磺化煤油的皂化微乳液为萃取剂。
关键词：钴、镍、微乳液体系、最优操作条件
Abstract : This paper introduces the microemulsion liquid membrane extraction of saponified P204 reaction mechanism of cobalt and nickel, the initial concentration of the extraction liquid, the external phase pH, P204 concentration, extraction time and separation factor than on the impact of cobalt and nickel, cobalt and nickel to determine Ions were the optimal operating conditions: extraction liquid pH 2.0, compared to V(o): V(a) to 2:1, single-stage extraction 10min, the initial concentration of liquid extract 0.5mol / L, 10 % P204 and the saponification 90% sulfonated kerosene microemulsion as extractant.
Keywords: Cobalt, Nickel, Microemulsion system, Optimal operating conditions
