摘要
本文以牛血清蛋白为科液,用酸、碱和表面活性剂作为清洗剂、对聚砜、聚丙烯腈等四种不同材质的超滤膜进行了污染和清洗实验,同时还研究了不同pH值对膜清洗效果的影响.结果表明:对于季铵化聚砜膜,用NaOH清洗效果较好;聚丙烯腈膜以HCI清洗效果为好;pH值在等电点附近,容易引起吸附.
In this paper,the three different cleaning agents were used to clean the ultrafiltra-tion membranes which had been fouled by bovine serum albumin (BSA). The effect of different pH values of the feed on cleaning membranes also was researched.
