摘　　要：A polyvinylidene fluoride (PVDF)/polyvinyl acetate (PVAc) blend ultrafiltration(UF) membrane was prepared by phase inversion method.The experimental results showed that the blend membrane significantly increased the water flux of PVDF membrane as well as kept the excellent chemical stability and high rejection for vitamin B 12 .A polyvinylidene fluoride (PVDF)/polyvinyl acetate (PVAc) blend ultrafiltration(UF) membrane was prepared by phase inversion method.The experimental results showed that the blend membrane significantly increased the water flux of PVDF membrane as well as kept the excellent chemical stability and high rejection for vitamin B 12 .
