The pollution resulting from the emergence of the contaminant perchlorate is anticipated to have a substantial effect on the water environment in the foreseeable future. Considerable research efforts have been devoted to investigating treatment technologies for addressing perchlorate contamination, garnering widespread international interest in recent decades. A systematic review was conducted utilizing the Web of Science, Scopus, and Science Direct databases to identify pertinent articles published from 2000 to 2024. A total of 551 articles were chosen for in-depth examination utilizing VOS viewer. Bibliometric analysis indicated that countries such as China, the United States, Chile, India, Japan, and Korea have been prominent contributors to the research on this topic. The order of ClO occurrence was as follows: surface water > groundwater > drinking water. Various remediation methods for perchlorate contamination, such as adsorption, ion-exchange, membrane filtration, chemical reduction, and biological reduction, have been suggested. Furthermore, the research critically evaluated the strengths and weaknesses of each approach and offered recommendations for addressing their limitations. Advanced technologies have shown the potential to achieve notably enhanced removal of perchlorate and co-contaminants from water sources. However, the low concentration of perchlorate in natural water sources and the high energy consumption related to these technologies need to be solved in order to effectively remove perchlorate from water.
预计污染物高氯酸盐的出现所造成的污染将在可预见的未来对水环境产生重大影响。近几十年来，人们投入了大量的研究精力来探索处理高氯酸盐污染的技术，引起了国际广泛关注。本研究采用 Web of Science、Scopus 和 Science Direct 数据库进行了系统综述，以确定 2000 年至 2024 年期间发表的相关文章。利用 VOS viewer 对 551 篇文章进行了深入研究。文献计量分析表明，中国、美国、智利、印度、日本和韩国等国家一直是该主题研究的主要贡献者。ClO 的出现顺序如下：地表水>地下水>饮用水。已经提出了各种用于高氯酸盐污染的修复方法，如吸附、离子交换、膜过滤、化学还原和生物还原。此外，该研究还批判性地评估了每种方法的优缺点，并提出了解决其局限性的建议。先进的技术已经显示出从水源中显著去除高氯酸盐和共存污染物的潜力。然而，需要解决天然水源中高氯酸盐浓度低和这些技术相关的高能耗问题，以便有效地从水中去除高氯酸盐。
