Mathematical Modeling of Facilitated Transport of Eu(III) ion by CMPO in Modified diluents as Extractant

Abstract

Abstract A simplified model has been developed to model the pertraction of Eu(III) through the flat-sheet supported liquid membrane (FSSLM) impregnated with CMPO in modified diluents as extractant. The solvent extraction studies of europium were performed under different experimental conditions and some of solvent extraction (SX) data were taken from literature as required to obtain some basic parameters of mathematical modelling for the mass-transfer process. The metal ion transport through liquid membrane is facilitated by diffusion and formulation of model is, therefore, governed by law of diffusion. Effect of various parameters on transport rate of Eu(III) ion, such as ligand concentration, feed acidity, diluent composition etc., has been predicted.
