The widespread of polybrominated diphenyl ethers (PBDEs) in the environment has caused rising concerns, and it is an urgent endeavor to find a proper way for PBDEs remediation. Various techniques such as adsorption, hydrothermal and thermal treatment, photolysis, photocatalytic degradation, reductive debromination, advanced oxidation processes (AOPs) and biological degradation have been developed for PBDEs decontamination. A comprehensive review of different PBDEs remediation techniques is urgently needed. This work focused on the environmental source and occurrence of PBDEs, their removal and degradation methods from water and soil, and prospects for PBDEs remediation techniques. According to the up-to-date literature obtained from Web of Science, it could be concluded that (i) photocatalysis and photocatalytic degradation is the most widely reported method for PBDEs remediation, (ii) BDE-47 and BDE-209 are the most investigated PBDE congeners, (iii) considering the recalcitrance nature of PBDEs and more toxic intermediates could be generated because of incomplete degradation, the combination of different techniques is the most potential solution for PBDEs removal, (iv) further researches about the development of novel and effective PBDEs remediation techniques are still needed. This review provides the latest knowledge on PBDEs remediation techniques, as well as future research needs according to the up-to-date literature.
多溴二苯醚（PBDEs）在环境中的广泛分布引起了人们的关注，因此寻找一种合适的 PBDEs 修复方法是当务之急。已经开发了各种技术，如吸附、水热和热处理、光解、光催化降解、还原脱溴、高级氧化工艺（AOPs）和生物降解，用于 PBDEs 的去污。因此，非常需要对不同的 PBDEs 修复技术进行全面的综述。本工作重点介绍了 PBDEs 的环境来源和存在、从水和土壤中去除和降解的方法，以及 PBDEs 修复技术的前景。根据从 Web of Science 获得的最新文献，可以得出以下结论：（i）光催化和光催化降解是报道最多的 PBDEs 修复方法；（ii）BDE-47 和 BDE-209 是研究最多的 PBDE 同系物；（iii）考虑到 PBDEs 的顽固性和不完全降解可能会产生更有毒的中间产物，因此不同技术的结合是去除 PBDEs 的最有潜力的解决方案；（iv）需要进一步研究开发新型有效的 PBDEs 修复技术。本综述根据最新文献提供了 PBDEs 修复技术的最新知识以及未来的研究需求。
