Process for preparing inorganic particulate adsorbent and process for treating nuclear reactor core-circulating water

Abstract

An inorganic particulate adsorbent of a titania-alumina system for treating a superheated water containing radioactive materials such as cobalt ions, which is free from release of corrosive impruities, and which has a high adsorption capacity of radioactive materials and a high mechanical strength is prepared by hydrolyzing a titanium alkoxide and an aluminum alkoxide, thereby forming a hydrous titanium oxide and a hydrous aluminum oxide, respectively; precalcining the hydrous titanium oxide and aluminum oxide, mixing and molding the resulting titania and alumina into a particulate mixture thereof having a titania mole fraction of 0.2-0.9, and calcining the particulate mixture at 500.degree.-700.degree. C. This absorbent is effectively used in treating boiling water-type nuclear reactor core-circulating water to remove radioactive substances therefrom.
