摘要
本研究首次通过CiteSpace分析水环境中汞的研究现状,总结了研究热点和前沿.从中国知网、万方、维普 3 大中文数据库和Web of Science Core Collection(WoSCC)检索了 2008-2023 年与水环境中汞有关的研究,检索到相关文献 697 篇.使用CiteSpace生成了作者/国家/机构之间的合作网络图谱,获得了关键词共现以及聚类图谱.结果表明:1)论文最高产者所发表的文章为8 篇,截至目前尚未形成核心作者团队;2)中国和中国科学院大学是该领域的领先国家和机构,分别发表了450 篇和21 篇论文;3)研究热点集中在汞离子、甲基汞、沉积物、原子荧光法、吸附以及水生生物.基于CiteSpace的研究结果,发现了国家、机构和作者之间的密切合作.目前主要研究趋势为水环境中汞的检测方法和去除技术,因此,未来应更加重视高性能纳米材料的制备和汞离子监测网络的完善,建立更加完善的汞离子监测预警方法.
Abstract
In this study,CiteSpace was used to analyze the research status of mercury in water environment for the first time and summarize the research hotspot and frontier.Studies related to mercury in the water environment from 2008 to 2023 were searched from three Chinese databases:CNKI,Wanfang,VIP,and the Web of Science Core Collection(WoSCC),697 relevant literatures were retrieved.CiteSpace was used to generate the cooperative network map among author/country/institution,and the keyword co-occurrence and clustering map were obtained.The results show that:1)The most prolific author has published 8 articles and has not formed a core author team up to now;2)China and the Chinese Academy of Sciences are the leading countries and institutions in this field,with 450 and 21 papers published,respectively;3)Research focuses on mercury ion,methylmercury,sediment,atomic fluorescence,aquatic organisms and adsorption.Based on the findings of CiteSpace,the study found closed collaboration between states,institutions and authors.At present,the main research trend is the detection method and removal technology of mercury in water environment.Therefore,in the future,more attention should be paid to the preparation of high-performance nanomaterials and the improvement of mercury ion monitoring network,so as to establish a more perfect mercury ion monitoring and early warning method.
