Ionic liquid A327HCl was generated by reaction of tertiary amine A327 and HCl, and the liquid-liquid extraction of indium(III) from the HCl medium by this ionic liquid dissolved in Solvesso 100 was investigated. The extraction reaction is exothermic. The numerical analysis of indium distribution data suggests the formation of A327HInCl in the organic phase. The results derived from indium(III) extraction have been implemented in a supported liquid membrane system. The influence of the stirring speed (600-1200 min), carrier concentration (2.5-20% v/v) in the membrane phase, and indium concentration (0.01-0.2 g/L) in the feed phase on metal transport have been investigated.
通过叔胺 A327 与 HCl 的反应生成离子液体 A327HCl，并研究了溶解在 Solvesso 100 中的这种离子液体从 HCl 介质中萃取铟(III)的液-液萃取。萃取反应是放热的。铟分布数据的数值分析表明，在有机相中形成了 A327HInCl。从铟(III)萃取中得到的结果已应用于支撑液膜系统。考察了搅拌速度（600-1200min）、膜相中的载体浓度（2.5-20%v/v）以及料液中铟浓度（0.01-0.2g/L）对金属输送的影响。
