Analysis of research status and trend of mercury in water environment based on CiteSpace
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.
