| 摘 要： | 采用吸附-两性模型探讨了聚电解质-离子配位体的组成，指出了阴、阳离子因吸附到聚电解质上形成聚电解质-离子配位体，其在膜表面的吸附，导致膜表面的荷电，得出了络合超滤对离子截留的截留机理除了络合效应外，可能还与膜表面的静电相互作用有关。分析了络合超滤软化工艺取代反渗透阻垢工艺的可行性。

| Abstract: | The component of polymer electrolyte-ion complex was discussed by the adsorption-amphoteric model. It was pointed out that polymer-anion complex existed because of anion adsorption onto surface polymer. The membrane might be charged as polymerion complex adsorption onto membrane surface. Therefore the mechanism of complex uhrafiltration could be depend on the complex and static electric effect. It was discussed that complex ultrafiltration soften process instead the adding anti-scale agents process in the reverse osmosis system. |
