聚咪唑／有序介孔碳互穿网络复合材料吸附 U（Ⅵ）的性能研究
Study on Adsorption of U (Ⅵ) f rom Aqueous Solution by Polyimidazole/Ordered Mesoporous Carbon Composite with Interpenetrating Framework
摘要
Abstract
The polyimidazole/ordered mesoporous carbon composite with interpenetra‐ting framework (AIM/OCMK‐3) was prepared by functionalizing mesoporous carbon (OCMK‐3) via radical polymerization . AIM/OCMK‐3 was characterized by FT‐IR , SEM and N2 adsorption‐desorption techniques . The effects of different experimental parameters such as initial pH ,initial concentration of U (Ⅵ) ,contact time and tempera‐ture on adsorption were investigated .The results show that AIM/OCMK‐3 show the highest U (Ⅵ) adsorption capacity at initial pH of 4.0 and contact time of 30 min ,and adsorption capacity increases from 40.90 mg/g to 213.01 mg/g after functionalizing . HCl is the preferred elution solution ,AIM/OCM K‐3 has good stability in the process of uranium in adsorption and desorption ,and AIM/OCM K‐3 can be reused .关键词
