摘　　要：为明确地下水脱砷技术研究现状及未来发展趋势,采用文献计量学方法统计分析了Web of Science(WoS)数据库中2008—2020年发表的关于地下水脱砷技术的文献资料,并从年度发文量、发文机构、发文期刊、发文作者以及论文关键词等方面进行分析。结果表明:WoS数据库中地下水脱砷技术方面的研究型论文共1501篇,年度发文量总体呈上升趋势;中国、美国和印度为发文量排名前3的国家;共计1503家研究机构、4875名作者参与地下水脱砷技术研究,其中高等院校为主要研究机构,而高校教师与硕士、博士研究生则为研究的主力军;关键词分析表明,吸附和电絮凝技术是地下水脱砷的主流方法,其中零价铁材料作为吸附剂是贯穿2008—2020年的研究热点;通过突现分析得出,二元甚至多元氧化物和纳米复合材料的制备将成为未来地下水脱砷技术研究的热点方向。To clarify the research status and future development trend of arsenic removal from groundwater,the bibliometric method was used to analyze the literature on arsenic removal from groundwater published in the Web of Science(WoS)database from 2008 to 2020,and the comprehensive analysis was conducted from the aspects of the annual number of articles published,publishing organizations,journals,authors,and keywords.The results indicated that:in WoS database,there were 1501 research papers on arsenic removal from groundwater,and the annual number of publications was on an overall upward trend;the top three countries in terms of publication volume were China,the United States and India;a total of 1503 research institutions and 4875 authors participated in the research of arsenic removal from groundwater,in which universities were the main research bases,and university teachers,postgraduate students werethe main force of the research.Keywords analysis showed that the adsorption and electrocoagulation technology were the mainstream methods for arsenic removal from groundwater,the zero-valent iron materials were popular adsorbents applied in the research from 2008 to 2020.At the same time,the emergence analysis showed that the preparation of binary or even multiple oxides and nanocomposites would become the frontier hotspot in the research of arsenic removal from groundwater.
