Abstract

By reaction of HCl and the tertiary amine HA324, an ionic liquid denoted HA324HCl was generated and used in the transport of indium(III) from HCl solutions. Metal transport experiments were carried out with a supported liquid membrane, and several variables affecting the permeation of indium(III) across the membrane were tested: stirring speed, metal and acid concentrations in the feed solutions and the carrier concentration in the supported organic solution. The metal transport results were also compared with those obtained using different carriers in the solid support. A model that described indium(III) transport across the membrane was proposed, and the corresponding diffusional parameters were estimated.

摘要

通过 HCl 和叔胺 HA324 的反应，生成了一种离子液体，记为 HA324HCl，并将其用于从 HCl 溶液中传输铟（III）。使用支撑液膜进行了金属传输实验，测试了影响铟（III）透过膜渗透的几个变量：搅拌速度、进料溶液中的金属和酸浓度以及支撑有机溶液中的载体浓度。还将金属传输结果与在固体支撑中使用不同载体获得的结果进行了比较。提出了一个描述铟（III）透过膜传输的模型，并估计了相应的扩散参数。
