摘要
制备了掺杂导电聚苯胺可剥离膜,首次采用涂膜、电解联用去污方法,进行涂膜电解去除渗透到核设施金属材料内部形成氧化物的铀。在膜中,聚苯胺、盐酸、EDTA-2Na含量各为4%、0.5%～1%、1%;电解电压2.3V、电解时间25min～30min时,其去污率可达99%。优于其它的方法。
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.
