Abstract
A process for preparing a crystalline layered hydrogenphosphate in a shortened period of time in high efficiency, which comprises reacting a tetravalent metal compound with phosphoric acid or its salt at an elevated temperature with introducing steam into the reaction system. Crystalline layered cerium(IV) bis(hydrogen-phosphate), particularly cerium(IV) bis(hydrogen-phosphate) dihydrate prepared by the above process, has an excellent ability of selectively adsorbing cesium ion, and is useful as a cesium ion adsorbent.
