摘要
针对电场作用下的超滤膜浓差极化现象 ,根据传递过程中的质量守恒定律并结合膜的吸附 -扩散分离理论 ,推导出了电超滤过程中的浓差极化比理论模型 ,并对该模型的影响因素如溶质的电泳速度和吸附 -扩散作用等进行了分析 .
According to the phenomenon of concentration polarization in electro_u ltrafiltration process, the model of concentration polarization ratio was establ ished based on the principle of mass conservation mechanism and the theory of ad sorption_ diffusion.The influence factors of concentration polarization ratio such as s olute electrophoresis rate and adsorption_diffusion were analyzed.
