| Abstract: | Electrically conductive PAn, doped with HCl, strippable coating was prepared. This is for the first time used for the decontamination the uranium pollution on the stainless steel surface of the equipment in nuclear industry, through coating and electrolysis. Results indicate that the decontamination efficiency is more than 99% when PAn, HCl and EDTA-2Na contents are 4%, (0.5%)~1% and 1%, respectively, and electrolytic voltage and electrolytic time are (2.3) V and 25 min~30 min, respectively. The problem of secondary contamination of the radioactive waste water was solved by electrochemical method. It compares favorably to other methods. |
