中文摘要
放射性污染是核能利用过程中的重要问题,放射性核素在环境中的迁移转化关系到环境污染和人类健康。多孔碳材料由于其具有的独特性能在放射性污染治理方面有重要应用前景。本项目拟从结构设计入手,制备并筛选出几种对放射性核素具有高吸附性和高选择性的无机-有机杂化碳胶囊材料,系统研究不同环境条件下材料对关键放射性核素选择性吸附和迁移转化影响,揭示无机-有机杂化碳胶囊材料结构和功能基团与放射性核素作用的构效关系,利用先进的表征技术和理论计算,从分子水平上明晰材料对放射性核素吸附的界面作用机理,阐明材料结构对放射性核素在环境中迁移转化影响,并进一步将筛选的无机-有机杂化碳胶囊材料用于真实环境中放射性核素的环境污染治理和评价研究。通过该项目的实施,为我国放射性污染治理提供先进的功能化材料、关键的新原理、新方法、新技术和典型示范。
英文摘要
Radioactive pollution is one of the most important problems in the utilization of nuclear energy. The transport of radionuclides in the natural environment is related to environmental pollution and human health. Therefore, extraction of radionuclides from aqueous solution has recently received extensive attention in the nuclear pollution field. Nanostructured porous carbon materials find applications in radioactive pollution management due to their low density, physical and chemical stability, micropores and/or mesopores. Among mesoscale structures, discrete, hollow capsules, referred to as hollow porous carbon capsules, have garnered considerable attention. This well-defined pore space can be utilized for molecular storage and separations. In this project, we propose to synthesize hybrid inorganic-organic hollow porous carbon capsules (HIOPCC), which have high and selective sorption properties to radionuclides. The effect of the HIOPCC on the sorption and transport of radionuclides in the environment will be studied intensively to understand the interaction mechanism of radionuclides with HIOPCC, especially the effect of the structures and functional groups on radionuclides interaction with HIOPCC. Advanced characterization methods and theoretical studies will be employed for understanding the mechanism of radionuclides on the solid interfaces at a molecular level. This is a completely new research direction and is an ambitious stretch beyond current activities. This proposal creates avenues for the rational design of highly active hybrid inorganic-organic hollow porous carbon materials, as well as new theory and techniques for radioactive pollution management.
