在可预见的将来,由于污染物高氯酸盐的出现而产生的污染预计将对水环境产生重大影响。大量的研究工作已经致力于研究解决高氯酸盐污染的处理技术,近几十年来引起了广泛的国际关注。利用科学网进行了系统评价,Scopus,和科学直接数据库,以确定2000年至2024年发表的相关文章。总共选择了551篇文章用于利用VOS查看器进行深入检查。文献计量分析表明,中国等国家,美国,智利,印度,Japan,韩国一直是这一主题研究的重要贡献者。ClO4-的发生顺序为:地表水>地下水>饮用水。高氯酸盐污染的各种修复方法,如吸附,离子交换,膜过滤,化学还原,和生物还原,有人建议。此外,该研究严格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显著提高从水源中去除高氯酸盐和共污染物的潜力。然而,为了有效去除水中的高氯酸盐,需要解决天然水源中高氯酸盐浓度低和与这些技术相关的能耗高的问题。
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 ClO4- 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.
