摘　　要：核电站运行过程中产生的放射性废物的安全处置问题,长久以来一直是全世界面临的一个前沿且颇具难度的研究课题.本文全面回顾了近年来长寿命核素锝-99及其类似物铼在地下水中的原位固定机制研究进展,对其涉及的吸附、还原和晶体掺杂3种主要固定机制进行了总结,并在此基础上对锝在地下水中的修复进行了展望,提出了下一步研究需要开展的方向.The safe disposal of radioactive waste generated during the operation of nuclear power plants has long been a cutting-edge and challenging research topic worldwide.This paper provides a comprehensive summary of recent advances in the mechanisms of technetium-99 in-situ immobilization.The three main mechanisms involved in technetium-99 immobilization are adsorption,reduction,and incorporation.Building upon these findings,the paper presents the prospects for technetium remediation in groundwater and identifies future research directions that need to be pursued.
