The polyamide composite membranes were prepared from m-phenylenediamine aqueous and trimesoyl chloride hexane solution through interfacial polymerization technique on the polysulfone hollow fiber ultrafiltration supporting membrane. The effects of different types, different concentrations of alcohols additives on the properties of reverse osmosis composite membrane separation. The experimental results indicated that different types of alcohol additives on the retention properties of composite membrane is different; the certain concentration of alcohol additives can be retained in the membrane properties of the same circumstances, so that membrane water flux increased 5-10 times.
