Preperation and Characterization of Cation/Anion Exchange Membrane for Electroadsorption-Deionization Process

The electrodeionization process is a mixture of ion exchange resin method and electrodialysis. There are a cation exchange membrane and an anion exchange membranes for electrodialysis, and cation and anion exchange resin filling in between two films to prepare a module. And Homogenous size distribution and the equivalent ratio of the ion exchange resin are also very important factor in determining the performance of the module. On the basis of these point, EAD (Electroadsorption-deionization) process module using the bipolar membrane with the ion exchange resin is produced thesedays. We prepared on the rubber polymer to improve the ion exchange capacity than the module currently produced. So, Sulfonated and aminated SEBS polymer (Poly styrene-ethylene-butylene-styrene triblock copolymer) was used to prepare the cation and anion exchange membrane in the module. Thus, this study is information on the cation and anion exchange membrane prepared blending the particles introduced into the ion exchange capacity and the high ion exchange capacity polymer to improve the performance of the module.
