The removal of some polyoxyethylated nonionic surfactants in aqueous solution were studied by reverse osmosis process using cellulose acetate membrane.<BR>The results were as follows : <BR>1) The permeability showed the high values when the carbon number of alkyl groups on the alkyl-phenyl ether and the alkyl ether surfactants was low, and as the carbon number of alkyl groups increases the permeability was tendencies to be lower.<BR>As the moles of ethylene oxide increases, the permeability comes to high, and the moles of ethylene oxide showed little difference in 20 to 40moles range.<BR>2) The rejection of the alkylphenyl ether and the alkyl amine surfactants were observed better than that of alkyl ether. The relation between the moles of ethylene oxide and the rejection of surfactants were little.
