Description
Summary:The efficiency of 12 different reverse-osmosis membranes for removing polar low-molecular-weight organic compounds from aqueous solution. Separation of these compounds was not as effective as those of inorganic salts for all the membranes tested. The aromatic-polyamide- and NP-type membranes gave 50 and 75 per cent separation respectively, of polar organic compounds, while cellulose-acetate membranes removed only 13-27 per cent. The separation of a given organic compound with a given membrane depends on the chemical nature of the molecule as well as the characteristics of the membrane.
