摘要：
Ionic liquid A327H(+)Cl(-) 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 A327H(+)InCl(4)(-) 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(-1)), 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.
