RESISTANT

TO ORGANIC An anion-exchange membrane was modified by sulfonating the surface of the base membmne, composed of styrene-divinylbenzene copolymer and polyvinylchloride. before its chloromethylation and the subsequent quartemization. The following three points are discussed: (I) effect of surface treatment with concen-Irated sulfuric acid to protect the membrane against organic fouling, (2) relation between sulfonating conditions at the membrane surface and the properties of the modified anion-exchange membrane. and (3) evaluation of the modified anionexchange membrane. INTRODUCXION It is well known that electrodialy& * Presented at the International Symposium on Fresh Water from the Sea,
