有机、重金属污染物同时吸附的前沿态势文献计量分析

A Bibliometrical Analysis of the Exploration Research of Simultaneous Adsorption of Organic Pollutants and Heavy Metal Ions

为了探索有机、重金属同时污染的研究现状和热点动态,以Thomson Reuters公司Web of Science信息平台提供的SCIE(网络版)数据库为数据源,运用Thomson Data Analyzer(TDA)和UCINET软件对1992年—2017年1月4日SCIE收录的有机、重金属同时吸附的研究论文进行数据挖掘和定量分析。结果显示,(1)国际上关于有机、重金属污染物同时吸附的研究分为初步研究期(1992—2000年)、稳步发展期(2001—2011年)和高速发展期(2012—2016年)3个阶段;年均发文量呈指数增加趋势,第3阶段达到176.8篇/年。(2)3个阶段所对应的研究主题分别为水污染处理、重金属污染和有机-重金属污染,且同时吸附是高速发展期研究的重点,并衍生出光催化和砷污染等研究主题。(3)中国的发文量从2001年开始超过美国成为主要研究力量,且中国科学院和浙江大学、中国科学院和湖南大学分别为稳步和高速发展期发文的主力机构;2012—2016年之间中国的总发文量再次达到最高(323篇),年发文量也达到了历史最高(64.6篇/年)。在亚洲国家中,日本也是这一领域研究的主要力量。(4)有机、重金属污染修复一直是科研的主流方向,2012—2016年的研究热点是重金属离子的同时吸附、零价铁对Cr(Ⅵ)的吸附效应、废水处理中的纳米过滤和有机污染物的光催化,主题之间紧密联系的研究点有纳米颗粒对有机、重金属的吸附,同时其交叉和衍生领域是未来研究的创新点。

Abstact： To understand the current status and hotspot of simultaneous adsorption of organic and heavy metal pollution research, papers （from 1992 to 2017.1.4） related to the topic of simultaneous adsorption of organic pollutants and heavy metal ions were analyzed, which were based on SCIE databas proveded by Web of Science information platform （online） of Thomson Reuters. Thomson Data Analyzer and UCINET were used for data processing and quantitatively analysis. The results showed that, （1） Internationally, studies of simultaneous adsorption could be divided into three stages, which were initial study stage （1992—2000）, steady development stage （2001—2011） and high-speed development stage （2012—2016）. The annual number of research articles increased exponentially and reached 176.8 articles per year in the third stage. （2） Research topic in three stages were water pollution treatment, heavy metal pollution adsorption, and organic and heavy metal pollutant simultaneous adsorption, respectively. Moreover, photocatalysis and arsenic pollution treatment were derived in high-speed development stage. （3） From 2001, papers published by China exceeded United States, which made China become the main strength of the study of pollution adsorption. Researches were mainly from the Chinese Academy of Sciences and Zhejiang University, the Chinese Academy of Sciences and Hunan University in steady development stage and high-speed development stage, respectively. In addition, papers publised from 2012 to 2016 by China reached a maximum of 323 articles, and its annual output reached 64.6 articles. Japan was another major research force in this field amonng Asian countries. （4） The main research direction was remediation of organic and heavy metal pollution. The current research hotspots were simultaneous adsorption of organic and heavy metal pollution, the effect of Cr（Ⅵ） adsorption on zero-valent iron, nanometer filter in the waste water treatment and photocatalytic of organic pollutant. Furthermore, the adsorption of nanoparticles on organic and heavy metals is closely related research points of each subject, the cross-over studies and derivative fields will be the innovation points in the future.
