从阴阳膜层内基本离子即盐正负离子和水离子 (H+,OH-)的传递过程着手 ,建立了几种常见物理构型的双极膜理论电压降模型 ,并对模型进行分析 ,提出了降低双极膜水解离电压的有效途径 .特别是对两性氢氧化物、高分子弱酸碱的水解离催化作用进行了理论解释 ,提出了催化作用是基于“自由溶液中水解离速率常数值增大”的观点 ,并提出了双极膜水解离催化剂的筛选依据 . Starting from the transfer process of the basic ions in the yin and yang membrane, that is, the transfer of salt ions and water ions (H +, OH-), several bipolar membrane voltage drop models with common physical configurations were established, and the model was analyzed. Reduce the bipolar membrane hydrolysis voltage from the effective way.Especially the amphoteric hydroxide, polymer weak acid-base hydrolysis of the catalytic role of a theoretical explanation, the proposed catalytic action is based on the “free solution of the hydrolysis rate constant increase Big ”point of view, and put forward the bipolar membrane hydrolysis catalyst screening basis.
