【摘要】 本文着重研究了表面活性剂溶液物化性质以及膜材质和操作条件对表面活性剂超滤行为的影响。实验表明,超滤膜对溶质的分离不仅是筛分作用,而且溶质与膜表面间的相互作用和溶质对界面性能的影响都对膜分离行为有影响。根据表面活性剂溶液的物化特性,可选用适当膜达到较理想的分离效果。更多还原

【Abstract】 The effect of the physicochemical properties of the surfactants, membrane materials and operating condition on their ultrafiltration behaviors were studied. The UF performances depend on the membrane pore size, the interaction between solute and membrane and the effect of the surfacatnts on the interfacial properties. The membrane which is appropriatoing for treatment of the surfactant solution may be selected according to the physico-chemical properties of the surfactants and their ultrafitration behaviors.更多还原
