摘　　要：介绍了混合萃取剂的组成 ,考察了萃取剂浓度、相比、平衡时间以及料液 pH值对In萃取及In、Fe分离的影响 .在最佳操作条件下 ,经过 2级逆流萃取 ,98%以上的In得到提取 .A constitution of the mixer extractant concentrations,phase ratio,equlibrium time and pH value of solution on the extraction of indium and the separation of indium-iron are investigated in this paper.Under the best working conditions,more than 98% of indium was extracted by two-stage counter-current extraction,and the anti-aging properties of extractants after having been recycled many times were investigated further.
