摘要: The aim of this study is to investigate the influence different composition cellulose acetate phtalate (CAP) on membrane structural properties polysulfone (PSf) which in turn affect separation performance PSf/CAP blend membrane. membranes were prepared by using casting solutions contain 17 wt% polymer via wet phase inversion process. results showed that increasing CAP increased molecular weight cut-off (MWCO), average pore size and density then protein solution permeate fluxes but reduced proteins rejection membranes. Pure PSf membranehas lowest compared This characteristic contributed decrease permeation flux increase rejection.
