摘　　要：活性炭作为核电站放射性碘的主要吸附材料,能有效去除放射性碘。而我国核电站大多位于气候潮湿的沿海地区,较大的环境湿度会对活性炭的吸附效率产生严重影响。因此,对核级活性炭进行疏水性改性,来解决核电站活性炭对放射性甲基碘吸附效率受环境湿度影响的问题是很有必要的。文章通过国内外文献报道,综述了活性炭改性的方法,分析了目前在活性炭疏水性改性方法中存在的问题,并提出针对核级浸渍活性炭疏水性改性方案。As the main adsorption material of radioactive iodine in nuclear power plant,activated carbon can effectively remove radioactive iodine.However,most of the nuclear power plants in China are located in the coastal areas with humid climate,and the higher environmental humidity will have a serious impact on the adsorption efficiency of activated carbon.Therefore,it is necessary to modify the hydrophobicity of nuclear grade activated carbon to solve the problem that the adsorption efficiency of radioactive methyl iodine by nuclear power plant activated carbon is affected by environmental humidity.Based on the literature reports at home and abroad,this paper summarizes the methods of activated carbon modification,analyzes the problems existing in the current hydrophobic modification methods of activated carbon,and puts forward the scheme of hydrophobic modification of nuclear grade impregnated activated carbon.
