摘要

通过对PAA-g-ZrO2复合膜过滤牛血清蛋白过程的污染阻力及其分布分析揭示接枝聚丙烯酸（PAA）对ZrO2膜抗污染性能的影响规律。结果表明：PAA-g-ZrO2复合膜和ZrO2膜的总阻力均随着过滤时间的延长而增加，但是PAA-g-ZrO2复合膜总阻力的增加趋势明显低于原ZrO2膜，同时，PAA-g-ZrO2复合膜的内部污染阻力Rif所占比例下降为原ZrO2膜的一半，这表明PAA接枝到ZrO2膜表面明显降低了膜孔内堵塞的内部污染，提高了膜的抗污染和易清洗性能。此外，溶液的pH值对PAA-g-ZrO2复合膜的污染阻力及其分布有着明显影响，当溶液pH值为8.0时，PAA-g-ZrO2复合膜几乎不存在膜孔堵塞污染。

Abstract

Fouling of PAA-g-ZrO2 composite membrane by BSA solution was investigated in conjunction with analysis of membrane total resistances and resistances distribution. The total resistances of the PAA-g-ZrO2 composite membrane and ZrO2 membrane increased with increasing filtration time

but the growth trend of the PAA-g-ZrO2 composite membrane total resistances was lower than that of the ZrO2 membrane. The fouling resistance of the ZrO2 membrane was Rcp (concentration polarization resistance)-dominant

while Rcp and Rm (membrane resistance) controlled the PAA-g-ZrO2 composite membrane separation process. The internal plugging resistance (Rif) of the PAA-g-ZrO2 composite membrane was just half of that of the ZrO2 membrane. The membrane resistance of PAA-g-ZrO2 composite membrane increased with increasing pH. The densely packed brush-shaped structure of the PAA chains was considered to be responsible for reducing the protein adsorption on the membrane surface. Furthermore

the PAA-g-ZrO2 composite membrane displayed high pH-sensitivity for BSA solutions

and could resist protein fouling in high pH applications.
