双极膜电渗析在醇水体系的应用研究进展
Progress of bipolar membrane electrodialysis for non-aqueous systems
摘要
Abstract
As a high-performance composited membrane,bipolar membrane has been widely used for the conversion of salt into acid and alkali,energy storage and conversion,and acid-base flow battery.Under reverse voltage bias,water molecules in the middle layer of bipolar membrane in aqueous system can be dissociated into H+and OH-,and cooperate with anion and cation exchange membrane to form bipolar membrane electrodialysis,which is widely used in the desalination and acidification of high-salt wastewater.In addition to the aqueous system,bipolar membrane electrodialysis can also be used in water-alcohol system,such as the production of water insoluble organic acids.Meanwhile,the bipolar membrane can also realize the dissociation of alcohols into hydrogen ions and alkoxide ions,which is applied to the production of metal-alkoxides and green synthesis of organic chemicals.However,there are fewer studies that summarize the application of bipolar membrane in alcohol water systems.This review focuses on the progress of bipolar membranes electrodialysis in alcohol water systems,comparing the mechanism and electrochemical properties of water and alcohol dissociation.Moreover,it also points out the bottlenecks of alcohol dissociation in bipolar membranes,including high dissociation resistance,serious coion leakage caused by the swelling of membrane layers,etc.Finally,it is necessary to in-depth elucidate the dissociation mechanism of the mixed system and to prepare alcohol-tolerance bipolar membranes to realize the wider application of the bipolar membrane water-alcohol mixed and the alcohol system.关键词
