PURPOSE: To obtain a homogenous and stable tin oxide adsorbing material high in adsorbing activity, excellent in cobalt adsorbing capacity and good in close adhesiveness, by a method wherein tin plating is applied onto a heat resistant and corrosion resistant carrier and a tin oxide thin layer is formed on the carrier by high temp. oxidation treatment.
CONSTITUTION: As a heat resistant and corrosion resistant carrier, a particulate body, a fibrous body or a block body comprising a metal such as Ti or ceramics such as alumina is used and, after tin plating is applied to said carrier, the plated carrier is subjected to high temp. oxidation treatment at 800W1,000°C to form a tin oxide thin layer on the carrier. This tin oxide is high in adsorbing activity while good in adhesiveness with the carrier due to solid phase reaction and a tin oxide inorg. adsorbing material excellent in practicality is obtained. Because this adsorbing material is high in adsorbing activity, excellent in Co adsorbing capacity and sufficient in function as a granulated body, it can be applied as the practical inorg. adsorbing material to a column for obtaining primary cooling water of a high temp. and high pressure nuclear reactor.
