摘　　要：采用羟基化预处理、铈盐引发和碱化预处理、Fe2+/H2O2引发两种引发体系,对聚砜(PS)膜和聚丙烯腈(PAN)膜进行表面接枝丙烯酰胺的改性,研究预处理和表面接枝改性对膜污染的影响。采用红外光谱和X光电子能谱对羟基化和接枝改性的膜表面进行表征。研究表明,表面预处理和接枝后,PS膜和PAN膜的水通量均有所下降,但提高了抗牛血清蛋白膜污染能力。Surface modification and fouling of polysulfone(PS) membranes as well as polyacrylomitrile(PAN)membranes were studied by grafting acrylamide with the initiating systems of Ce4+/-OH and Fe2+/H2O2 after pretreatment by K2S2O8 and alkaline respectively.The surface modified membranes were verified by infrared spectroscopy and X-ray photoelectron spectroscopy.Results showed that the anti-fouling ability of both PS and PAN membranes with respect to bovine serum albumin was improved after surface modification though the water flux was reduced.
