系统地研究了Gemini表面活性剂和传统非离子表面活性剂在胶束强化超滤(MEUF)的单一和混合体系中对苯酚的分离效率。本研究选用了总有效面积为0.08m2、截留分子量为10 kDa的平板膜。研究了进料组成(单一表面活性剂体系的表面活性剂浓度和混合表面活性剂体系的混合比例)对增溶和过滤效率的影响。用分配系数(D)、胶束相中苯酚浓度(Pm)、胶束相中表面活性剂浓度(Sm)、胶束负载量(Lm)和平衡分配常数(K)等参数评价了不同表面活性剂体系的性能。随着进料表面活性剂浓度的增加或非离子表面活性剂的加入，pH的增溶程度增大。
AbstractA systematic study has been conducted to have an insight into the separation efficiency of phenol with the help of Gemini surfactants and conventional nonionic surfactant in their single and mixed systems using micellar-enhanced ultrafiltration (MEUF). A flat sheet membrane with a total effective area of 0.08 m2 and a molecular weight cut-off of 10 kDa, was selected in this investigate. The effects of feed component (surfactant concentration for single surfactant system and mixed ratio for mixed surfactant system) on solubilization and filtration efficiency were researched. Some related parameters were used to estimate the performance of various surfactant systems, such as distribution coefficient (D), the phenol concentration in micellar phase (Pm), the surfactant concentration in micellar phase (Sm), the micelle loading (Lm), and the equilibrium distribution constant (K). With the increase of feed surfactant concentration or the addition of nonionic surfactant, the degree of solubilization of ph...
