Diffusion Permeability of Cation-Exchange Membrane in Different Solutions

Abstract

This work is devoted to study the effect of thermal conditions and concentrations on the diffusion permeability of a cation exchange membrane (MK-40) using sodium chloride (NaCl), sodium acetate (C 2 H 3 NaO 2 ) and acetic acid (CH 3 COOH) solutions, which are usually highly concentrated components of pigment yellow 13 of industrial wastewater. A cell containing two compartments was used to analyze the properties of membrane. The results showed that the maximum diffusion permeability coefficients for NaCl, C 2 H 3 NaO 2 , and CH 3 COOH were 6.08×10 -9 m 2 /s, 13.29×10 -11 m 2 /s, and 25.95×10 -11 m 2 /s, respectively. The increase in the CH 3 COOH solution concentration was found to improve the diffusion permeability. However, the NaCl and C 2 H 3 NaO 2 solutions exhibited decreases in diffusion permeability with solution concentration. There was a significant increase in diffusion permeability with temperature.

Application of Poly(Ethyl Eugenyl Oxyacetate) Compounds as the Ions Carrier for Heavy Metals Separation and Separation of Fe and Ni in Ferronickel Using Liquid Membrane Transport Method

“…The presence of other ions as interference in the Fe(III) ion solution also affects the decrease in transport percent of Fe(III) ion in the stripping phase. The reduction of this transport percent is related to some active groups in the membrane phase forming complexes with interference ions [19].…”
