摘要：
A treated permeable inorganic membrane having good chemical stability over a pH range of from 1 to 14. The monomolecular layer of organic acid material is formed on the membrane surface by contacting phosphonic acid having the formula RPO(OH).sub.2 ; phosphinic acid having the formula RR'PO(OH); monocarboxylic acids having the formula RCOOH; dicarboxylic acids having the formula R"(COOH).sub.2 ; or boronic acid having the formula RB(OH).sub.2.
