Study on decontamination of plutonium contaminated metal surface by cerium (IV) corrosion process
Description
To acquire optimal corrosion technical parameter, corrosion process experiment was conducted to stainless steel, carbon steel and cast iron. The experiment results showed nitric acid concentration of corrosion solution had stronger effect on oxidation capability and the stronger oxidation capability was acquired when nitric acid concentration of corrosion solution was 2 mol/L. Under 2 mol/L HNO3+ 0.05 mol/L cerium (IV), the corrosion depth of 10.1, 15.2 and 25.4 was obtained by means of 48 h corrosion process to stainless steel, carbon steel and cast iron, respectively. At the same condition, for plutonium contamination ranging from 0.48 Bq/cm2 to 0.68 Bq/cm2 fell to ranging from 0.06 Bq/cm2 to 0.08 Bq/cm2. Based the experimental results, it could be inferred that cerium (IV) corrosion process was a suitable method for decontamination of plutonium contaminated metal surface. (author)
