Using four types of low pressure reverse osmosis membranes (NS-300, NS-301, NTR-7450, NTR-729 HF), reverse osmosis concentration of eight kinds of aliphatic acids in aqueous solution were carried out. The effect of ratio of trimesoyl chloride and isophthaloyl chloride on membrane performance have been investigated in the fabrication of NS-301 membrane.
