Abstract
Inventia de fata se refera la un procedeu de obtinere a unor membrane schimbatoare de ioni eterogene. Procedeul, conform inventiei, are la baza policlorura de vinil si o rasina schimbatoare de ioni, supusa unui tratament termic prealabil, acestea putând fi utilizate în procesele de separare si purificare prin electroliza si electrodializa. Membranele au grosimi cuprinse între 0,25...0,45 mm si rezisnteta electrica pe unitate de suprafata cuprinsa între 2,6 si 49 om/cm supra 2.
