利用溶液相转化法,在铸膜液中加入分子筛NaA和PEG来协同提高聚砜超滤膜的水通量和截留率,研究了分子筛的含量对聚砜超滤膜的形貌结构,表面粗糙度,水通量,蛋白质截留率和亲水性的影响。利用场发射扫描电镜、扫描探针原子力显微镜、膜评价仪和接触角仪分别对该膜的形貌、水通量、蛋白质截留率和亲水性进行表征。结果表明分子筛含量从0g增加到3.0g,聚砜超滤膜的水通量从140L/（m2·h）提高到500L/（m2·h）,对胃蛋白酶的截留率从78.8%提高到92.7%,对牛血清蛋白的截留率从97.6%增加到99.0%以上。分子筛NaA可以协同提高聚砜超滤膜的水通量和蛋白质截留率。
This paper mainly aimed at improving the pure water flux and rejection of polysulfone (PSF) ultrafil tration membranes by adding PEG and zeolite additives into casting solution during the phase inversion process. The influences of different dosages of zeolite on morphology, surface roughness, hydrophilicity, mechanical strength, water flux and rejection to protein were investigated. Results showed that the dosage of zeolite in crease from 0 to 3.0g, the water flux of prepared membranes increased from 140 to 500L/(m2· h), and the re jection to pepsin increased from 78.8% to 92.7% and the rejection toBSAkept 99.0%. Pure water flux and re- jection of PSF ultrafiltration membranes could be improved simultaneously by adding PEG and zeolite additives into casting solution through phase inversion method.
