摘要： PROBLEM TO BE SOLVED: To improve the performance of a catalyst to decompose a decontaminant containing an organic acid in order to reduce the load on an ion exchange resin and to decrease wastes by accompanying the chemical decontamination of radioactive deposits.
SOLUTION: In the decomposition of the organic acid which is the decontaminant using the catalyst attached additionally with noble metals, from 10 mesh (opening of sieve mesh 1.68 mm) to 20 mesh (opening of sieve mesh 0.84 mm) are found as optimum grain sizes. The organic acid after the decontamination can be decomposed with high efficiency by applying the catalyst of such grain sizes and the shortening of the decomposition time, the downsizing of facilities and the evading of the degradation in water quality by the deterioration of the ion exchange resin are made possible. The organic acid used for the chemical decontamination can be efficiency subjected to the decomposition treatment in a short period of time by using the catalyst of the grain sizes. In addition, not only an oxalic acid but other organic acids, etc., can be efficiently decomposed.
