Study of the Transfer Reactions of the Ions on the Liquid/Liquid Interface Supported by the Ion-Exchange Membrane
Abstract: After years of constant exploration, ion exchange membrane not only made great progress of preparation method, but also has been greatly expanded of the application scope. And people are studying more functional and better performance ion exchange membrane actively and structure exchange membrane research more uses its binding ions. In the near future, ion exchange membrane electrochemical performance has been development rapid, such as: electrodialysis, electrocatalysis and desalination. In all aspects of modern life ion exchange membranes have great prospects for development, it also requires our constant study. Membrane ion selective permeability is one of the most important characteristics of ion-exchange membrane, is the basis for research other aspects. For this demand, the subject ion exchange membrane support liquid / liquid interface, and four-electrode system utilizing liquid ion exchange membrane supported research / liquid interface electrochemical window and selective ion transfer reactions. This topic is using the four-electrode system cyclic voltammetry and CHI660D electrochemical workstation environment, study ion exchange transfer reaction at ion membrane supported liquid / liquid interface.
KeyWords: ion transport; ion exchange membrane; voltammetry
