摘要：

The preparation and performance of reverse osmosis membrane of the chloromethylated/quaternized polysulfone were investigated. The membrane structures of cross section and skin were analyzed by scanning electromicrograph. The chemical structure of the polymers were confirmed by the infrazed spectrium analysis and element analysis. In further, the characteristics of quaternized polysulfone membrane, such as mechanical strength, resistance to chlorine and oxygen, long-term operation were tested. In the condition of low operation pressure 1.5MPa, the membrane had 93% salt rejection and 0.8m3/m2.d product rate for tap water.
