Separation method for rare-earths using high-voltage electrophoresis on paper strip; Methode de separation des terres rares par electrophorese a haute tension sur papier - support

Abstract

The equipment includes an electrophoresis set running at 3 000 V and 20 mA. Two cooling plates are used as heat exchanger, and a pneumatic pressure device to insure an uniform pressure on the paper strip laid flat. The mobilities and the separations of the rare earths in lactic, and, {alpha} hydroxy-isobutyric acid solutions are investigated on cellulose acetate strip. Better results are obtained with {alpha} hydroxy-isobutyric acid. The method is rapid and allows a fine fractionation of rare earth elements within less than an hour. A complete separation of a Ce - Pr - Nd - Pm - Eu mixture, and a Y - Tb mixture is obtained. (author) [French] L'equipement comporte un appareil d'electrophorese fonctionnant sous 3000 V a 20 mA.
