实验过程

An aqueous phosphoric acid solution prepared by diluting 200 ml of phosphoric acid solution in a concentration of 14 moles/liter by adding water to make up a volume of 500 ml was introduced into a three-necked flask of 1 liter capacity and heated and kept at 90° C. An aqueous solution of cerium (IV) sulfate, which was prepared separately by dissolving 22.9 g of a reagent-grade cerium (IV) sulfate monohydrate having a purity of 95% in 500 ml of water with admixture of 16 ml of a 18 moles/liter aqueous solution of sulfuric acid, was added dropwise into the aqueous phosphoric acid solution under agitation at a rate of 4 ml per minute so that precipitates were formed in the mixture. After completion of the dropwise addition of the cerium sulfate solution, the mixture in the flask was agitated for further 8 hours by keeping the temperature at 90° C. followed by filtration to collect the precipitates which were thoroughly washed with water and dried at room temperature.
