The treatment and recovery of pollutants in aquatic system is one of the greatest challenges for environmentalists throughout the world. In this study, solvent extraction of indium using phosphonium ionic liquid (Cyphos IL 104) as an extractant and its mathematical model was proposed for prediction of In(III) ion transport across a FSSLM (flat-sheet-supported liquid membrane). Solvent extraction experiments on indium have been carried out under various experimental conditions in order to assert some fundamental parameters using mathematical analysis for mass transfer process. Diffusion is the process which facilitates metal ion transport across liquid membrane, indicating the applicability of Fick's law of diffusion in model formulation. The influence of different parameters like composition of diluent, feed acidity, and ligand concentration on In(III) ion transport rate has been reported. At different extractant concentrations, the modeling outputs and experimental indium extraction were observed to be in reasonably good agreement.
水系统中污染物的处理和恢复是全世界环保主义者面临的最大挑战之一。在这项研究中，提出了用膦离子液体（Cyphos IL 104）作为萃取剂萃取铟的溶剂萃取及其数学模型，用于预测 In(III)离子在 FSSLM（平板支撑液膜）中的传输。为了使用数学分析对传质过程进行确认，在各种实验条件下进行了溶剂萃取实验，以确定一些基本参数。扩散是促进金属离子穿过液膜传输的过程，表明菲克扩散定律在模型公式中的适用性。报道了稀释剂组成、进料酸度和配体浓度等不同参数对 In(III)离子传输速率的影响。在不同的萃取剂浓度下，观察到模型输出和实验铟萃取之间具有相当好的一致性。
