摘要
制备出酸度- 13. 20 <H0 < - 11. 99 的SO42 /TiO2 固体超强酸,将其掺杂于导电高分子聚苯胺后制备出应用于核设施工业的放射性去污可剥离膜,得到满意的结果是其电导率达到7.01S/cm,涂膜湿法电解的放射性去污率高于94%,涂膜干法电解去污率高于97%。
We prepared the SO42-/TiO2 solid superacid whose acid strength was to be -13.75 0 42-/TiO2 superacid was an effective electrical conductive macromolecule. When used in the strippable coating film for decontaminating radioactive pollution, it got high decontamination ratio (>97%) and produced less waste needing disposal, as well as it wouldn't erode the substrate. Coating and electrolyzing the film in solution or in dry medium were effective method, and the latter was a more promising method for decontamination of radioactive pollution in nuclear industry.
