Abstract

In this experiment,the properties of BSA adsorption of PES membrane is studied.The amount of protein absorbed on the films were detected by bicinchonininc acid assay(BCA)method.The various films and dynam performance were observed by scanning electron microscope(SEM)and electron mightiness instrument.According of the increasing of PEG 20000 and PEG 400 ratio,Adsorption of BSA decreases and then increases,water flux of PES membrane increases and then drcreases,rejection of PES membrane between 97.93% to 99.39%.The experiment results show that the ratio of PEG 20000 and PEG 400 is 2,the best hydrophilicity and the least BSA adsorption of PES membrane.
