    摘要： An active material is disclosed which comprises a metal oxide/hydroxide surface having chemically bonded to reactive sites thereon a substantially monomolecular layer of organic acid molecules. Each organic acid molecule is chemically bonded to a reactive site on the oxide/hydroxide surface through a phosphorus-containing acid group selected from the group consisting of a phosphonic acid group and a phosphinic acid group. Each organic acid molecule also comprises an unreacted acid group oriented away from the metal oxide/hydroxide surface and selected from the class consisting of a phosphonic acid group, a phosphinic acid group, a sulfonic acid group, and a carboxylic acid group.

    摘要： A treated permeable inorganic membrane is disclosed comprising a permeable inorganic membrane capable of reacting with an organic acid. The treated membrane has good chemical stability over a pH range of from 1 to 14, is capable of controlling the flux through the membrane, has altered internal and external wetting properties of the membrane surface, and has controlled pore size due to the presence of a monomolecular layer of an organic acid material chemically bonded to the surface of the inorganic membrane. The monomolecular layer of organic acid material is formed on the membrane surface by contacting the membrane with an organic acid reactant selected from the class consisting of 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 ; boronic acid having the formula RB(OH).sub.2 ; and one or more precursors of the foregoing acids which decompose to form the acid functionality; where R comprises a 1-30 carbon-containing group, R' comprises hydrogen or a 1-30 carbon-containing group, and R" comprises a 2-30 carbon-containing group. Excess organic acid reactant not bonded to the underlying membrane surface is removed to ensure formation of said monomolecular layer of said organic acid material on the surfaces of said permeable inorganic membrane.
