PVDF membrane made from casting solution containing 16% PVDF and 0.05% LiCl was the thinnest, and it had the least flux (F) and flux reduction coefficients (m) and the most rejection (R) of blood serum albumen (BSA) under the experimental conditions.

• 在实验条件下；w(PVDF)为16%25；w(LiCl)为0.；05%25时；所得PVDF膜最薄；有最低的水通量(F)和水通量衰减系数(m)；以及最高的对牛血清白蛋白(BSA)的截留率(R)。 w(LiCl)小于0
