    ion exchange membrane
    en
    Definition insoluble membranous material on which ion exchange groups are bonded; the membrane is able to keep two different solutions physically separated and is simultaneously permeable to ions and water Reference "Toshikatsu Sata. Recent trends in ion exchange membrane research. IUPAC. Pure & App!. Chem., Vol. 58, No. 1 2, pp. 1 61 3—1626, 1986, http://pac.iupac.org/publications/pac/pdf/1986/pdf/5812x1613.pdf [11.10.2013]"
    Comment "Ion exchange membranes can be a) monopolar, which are subdivided into i) cation exchange membranes, which contain negatively charged groups, and ii) anion exchange membranes, which contain positively charged groups fixed to the polymer matrix or b) bipolar that contain on one side an anion exchange layer and on the other side a cation exchange layer.

    Definition membrane constituée d'un matériau généralement macromoléculaire, plus ou moins réticuléen un réseau tridimensionnel insoluble dans l’eau, sur lequel sont fixés de façon covalente des groupements fonctionnels ionisés appelés aussi des ions fixes, neutralisés électriquement par des ions mobiles de signe opposé appelés ions compensateurs ou contre-ions Reference "Elaboration et caractérisation d'une membrane cationique monosélective par modification chimique d'un film ETFE, Boulehdid Hanae, thèse, ULB, 2007-2008, http://theses.ulb.ac.be/ETD-db/collection/available/ULBetd-01142008-104454/unrestricted/Boulehdid.pdf [23.12.2013]"
