Abstract: The research progress in the aspect of the modification of mono-valent permselective anion-exchange mem-brane at present are summarized. The methods for the improvement of mono-valent permselectivity of anion-exchange membrane are expounded in detail,emphatically in four aspects,including blending modification,surface-coated mo-dification,electro-deposition surface modification and chemical grafting surface modification. The factors constrain-ing the development of the mono-valent permselective anion-exchange membrane are analyzed. At the end,it is point-ed out that clarifying modification mechanism and expanding new modification methods will be the future developing directions for the improvement of the mono-valent permselective separation capability of anion-exchange membrane.

Key words: mono-valent permselectivity, anion-exchange membrane, surface modification, electro-dialysis
