Abstract
Oxidation of Ce(III) with ozone in concentrated hydrochloric acid was studied. Ozonation of hydrochloric acid solutions containing CeCl3 and CsCl results in precipitation of crystalline Cs2CeCl6. The precipitate is not formed when chlorine-saturated hydrochloric acid solutions containing CeCl3 and CsCl are stored in the dark. Exposure of such solution to the radiation of a mercury lamp for several minutes results in precipitation of Cs2CeCl6. The mechanism of the ozonation of HClconc containing CeCl3 is discussed with consideration of radiation-chemical data.
