Abstract
The physico-chemical properties of an anion exchange membrane (ADS, Solvay) were studied in aqueous solutions containing both a mineral salt (10(-1) M NaCl) and an organic salt (10(-2) to 10(-1) M). The organic salt was a sod ium carboxylate or sulfonate bearing one or two aromatic rings. Measurement s of ion exchange, water content, electric resistance, self-diffusion and e lectrodiffusion fluxes were performed. According to the concentration, the organic anions with highly hydrophobic character can induce a poisoning of the membrane. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
