The effect of NaCl additive on the decontamination ability of Na₃P0₄ electrolyte

Using Na₃PO₄ solution as electrolyte, effect of NaCl additive and its concentration on the decontamination ability of an electrochemical process for radioactive contaminated stainless steel sheet was investigated. The results indicate that the decontaminate factor increases with the extension of time, and also with the addition of NaCl. The weight loss rate of stainless steel sheets with NaCl additive is always higher. While NaCl concentrations are 200 g/L and 250 g/L, the decontaminate factor and weight loss rate reach the max of 13.7 and 2.21% respectively. It shows that NaCl with a certain concentration can help improve the decontamination ability of Na₃PO₄ electrolyte. (authors)
