Abstract

A study of several methods of precipitation of cerium shows that the apparent purity of the precipitate is dependent upon the p~H~ of the solution. An attempt is made to evaluate the efficiency of the varying methods and it is found that the classical nitrate/bromate separation attains the highest efficiency of the procedures examined. The probable formation of a basic chloride during hypochlorite treatment of cerium is noted.
