From Table 2, one observes that the polymer coating film is effective for eliminating the radioactive pollutants. When combined with the electrolysis method, the decontamination ratio increased from 73% to 93%. Electrolyzing in dry medium yielded the best results, with a decontamination ratio higher than 97%, and producing waste that was much easier for further disposal. Therefore this method is a promising one which is worth exploring further (Table 3).
