去除水体中放射性核素的磁性纳米材料的研究进展

Research progress of magnetic nanomaterials for removing radionuclides from water

核医学实验、核医学治疗及核事故产生的放射性核素不可避免地释放到水体、土壤等自然环境中,对环境造成极大破坏,对人体的遗传、免疫、骨骼、神经系统等产生辐射损伤和化学毒性,严重危害人类健康。磁性纳米吸附材料具有优异的表面性质和磁响应性,被广泛用于去除水体中放射性核素的研究。笔者对磁性纳米材料去除水体中放射性核素的研究进展进行综述。

Radionuclides produced by nuclear medical experiments,nuclear medicine treatment and nuclear accidents are inevitably released into the natural environment such as water and soil,causing great damage to the environment and the genetic,immune,skeletal and nervous systems of the human body.With excellent surface properties and magnetic responsiveness,magnetic nano-adsorption materials are widely used in the removal of radionuclides from water.In this paper,the research progress of the magnetic nanomaterials for removing radionuclides from water is reviewed.
