Tan Ling-yan, Jindun Liu, Zhang Haoqing, Qihui Liang

Abstract

SPES/PSF ultrafiltration membrane was successfully prepared by the blend method,with sulfonated polyethersulfone(SPES) and polysulfone(PSF) as membrane material.The preparation technology of SPES/PSF blend ultrafiltration membrane was studied by means of uniform experiment design.The model equation of fluxes was obtained by means of regress analysis.On the basis of the model equation,the effects of blend ratio,polymer concentration,additive concentration etc.upon the fluxes were investigated by single factor simulation analysis.It was found the fluxes of the optimum SPES /PSF membrane was 93.1L/(m2.h) and 93.37% rejection to PVA.
