摘要
本文在膜的吸附-扩散分离模型的基础上讨论了浓差极化现象,得出了浓差极化比与溶质和膜表面相互作用的物化特性(K_A/K_B)有关的结论,给出了浓差极化比的理论公式。分析了溶质在膜表面优先吸附和受排斥情况下的浓差极化现象。
In this paper, the phenomena of concentration polarization was discussed on the basis of the membrane separation model of adsorptlon-diffusion. A conclusion has shown that concentration polarization rate is concerned with the physichemical characteristics of the interaction of solute with surface of membrane, a theoretic equation of the concentration polarization rate was given. The phenomena of concentration polarization under the conditions of preferential adsorption and repulsion on the surface of membrane were analysed.
