不同吸附材料对废水中Co2+的去除研究
Study on the removal of Co2+in waste water by different adsorption materials
摘要
Abstract
Radioactive cobalt(Co)is the main nuclide among the radioactive nuclides produced in the primary loop of nuclear power plants and it will be transferred to the decontamination liquid after the decontamination of the primary loop pipeline.By investigating the adsorption materials of Co2+,the adsorption effect of different adsorption materials was compared and analyzed,and the performance of different adsorption materials was clarified,which provided a basis for the research of absorption materials for Co2+in waste water.The results showed that:the adsorption capacity of minerals and biological adsorbents was small;metal oxides did not show adsorption performance under acidic conditions;the adsorption rate of ion exchange resin was slow;activated carbon had both fast adsorption rate and high adsorption,but it could not show good adsorption performance under acidic conditions,and the research of other carbon materials was still in the laboratory stage.In view of the above,it is suggested to use inorganic nanometer materials with strong stability,boron nitride and graphene oxide,as the base material to synthesize materials with level pore structure,and to carry out functional modification on this basis,so as to synthesize adsorption materials with high adsorption performance under harsh conditions such as or strong acid.关键词
