摘要:
Modified poly(vinyl alcohol) (PVA) membranes prepared by the 'solution technique' were tested for ethanol-water mixtures by varying the reaction density (X(cr) = 0.05, 0.1) at various temperatures. The results are compared with those of PVA membranes (X(cr) = 0.05) prepared by the technique of the GFT Company, Germany.
