Composite reverse osmosis membranes prepared by plasma polymerization of allylamine. Evaluation of membrane performance for the treatment of washwater and its components

摘要

AbstractReverse osmosis membranes prepared by plasma polymerization of allylamine–nitrogen mixtures over a porous substrate were evaluated for the rejection of components present in washwater. The membranes exhibited high rejections for sodium chloride, potassium chloride, detergent, and dextrose. High rejections of urea could be achieved, but only at a sacrifice of water flux. Lactic acid could also be rejected but caused a degradation of the plasma‐deposited la
