| Abstract: | Thin-film composite reverse osmosis membranes were developed by interfacial polymerization of metaphenylenediamine and polyacyl chlorides such as 5-chloroformyloxy-isophthaloyl chloride(CFIC),5-isocyanato-isophthaloyl chloride(ICIC),and 1,3,5-cyclohexanetriacyl chloride(CHTC).The properties of the resulting membranes were studied in terms of surface chemical structure,surface charge,pure water permeability,and salt rejection rate as well.Surface modification of the thin-film composite polyamide reverse osmo... |
