Autoradiographic study of ion-diffusion in ion-exchange membranes

An autoradiographic study was made of the diffusion of the ions 212Pb 2+, 241Am 3+ and 239Pu 4+ in ion-exchange membranes of polystyrenesulphonic acid type, as functions of the diffusion time, the temperature and the hydrogen ion concentration of the solution in contact with the membranes. The activ...

Summary:An autoradiographic study was made of the diffusion of the ions 212Pb 2+, 241Am 3+ and 239Pu 4+ in ion-exchange membranes of polystyrenesulphonic acid type, as functions of the diffusion time, the temperature and the hydrogen ion concentration of the solution in contact with the membranes. The activation energy of the diffusion process was determined from the temperature-dependence of the diffusion constant. Eine autoradiographische Studie von Ionen Diffusion des 212Pb 2+, 241Am 3+ und 239Pu 4+ in Ionen Austausch Membranen vom Polystyrensulfonsäure Typ wurde als Funktion der Zeit, Temperatur und Wasserstoffionen-konzentration der Lösung in Kontakt mit den Membranen durchgeführt. Die Aktivierungsenergie des Diffusionsprozesses wurde durch die Temperaturab-hängigkeit der Diffusionskonstante bestimmt. ; ЛOHHOЧ e;icy;ФФuЗicy;icy; З KhcyHOOБMe;HHЫЧ Me;MBPAHAЧ icy;cлOлHicy;лOcъ ABTPAлicy;Oгicy;PAфicy;Khcye;iicy HкOe; icy;ccлe;лOBAHicy;e; гicy;ффuзicy;icy; ;icy;OHOB 212 P 2+, 241AM 3+ icy; 239P 4+ B icy;OHOOбMe;H Hыч Me;MбPAHHч Ticy;лA лOлcTicy;POicy;cuicy;ъфOn y;OBOй кicy;cлOTы, B зABicy;cicy;i MOcTicy; OT BPe;Me;Hicy; лPe;MiHicy; лicy;ффuзicy;i cy;, Te;Mпe;PATuPы icy; кOHцe;HTPAцicy;icy; icy;OHOB BOдOPcдA PAcTBOPA HAчOдKhcyhi ecy;гccKhcy B кOHTAкTe; Me;MбPAHAMM. e;He;Pгicy;Khcy AкTicy;BAцicy;icy; дicy;& fcy;фuзicy;OHHOгO пPOцe;ccA OпPe;лe;лicy;лAcъ пO зABicy;cicy;MOcTicy; кOHs cy;TAHTы гicy;ффuзicy;icy; OT Te;Mпe;PATuPы.
