Abstract
The effects of post-treatment (including thermal treatment and base treatme nt) on the structure and performance of acrylonitrile-maleic anhydride (AN- MA) copolymer membrane were investigated. The confer flux decreased gradual ly (except the deviations when the temperature of thermal treatment was 50 degrees C or the time of thermal treatment was 50 min but rejection of bovi ne serum albumin increased slowly with increasing temperature or prolonging the time of thermal treatment. "The swelling effect of water in network" w as proposed to explain the deviations. AN-MA copolymer membrane is not resi stant to a base. However, the performance of the membrane can be adjusted b y treatment with a dilute base solution. Copyright (C) 2000 John Wiley & So ns, Ltd.
