基于文献计量的零价铁在我国水环境污染的修复研究热点分析

Zero Valent Iron Based on Literature Metrology Analysis of Research Hotspots on Remediation of Water Environmental Pollution in China

借助CNKI,利用文献计量学方法对2005~2020年15年间发表的零价铁在水环境污染修复相关文献,研究了零价铁修复环境污染在2005~2020年15年间,三个时间段(2005~2010、2011~2015、2016~2020)的发展与演变,对比不同时间段内零价铁环境修复技术发展的异同点。文献计量分析显示:零价铁环境修复历程早期主要以传统零价铁进行污染修复,主要集中于还原脱氯处理研究;逐渐进入零价铁与化学生物法联用的研究阶段,随后零价铁应用逐渐向表面改性,负载修饰发展,活性进一步加强,大大提高零价铁处理效率。历经十多年的迅猛发展,随着跨学科交叉融合不断增强,结合材料功能化,粒径尺寸纳米化为特征的新型零价铁复合材料制备。因地制宜施用将是零价铁在水环境污染修复研究中亟待突破的重要瓶颈。

With the help of CNKI, literature metrology method was used to study the literatures related to zero-valent iron in water environmental pollution remediation published during the 15 years from 2005 to 2020. The development and evolution of three periods(2005~2010, 2011~2015 and 2016~2020) were compared to compare the similarities and differences in the development of zero-valent iron environmental remediation technology in different periods.Bibliometrical analysis shows that in the early stage of zero-valent iron environmental remediation, pollution remediation was mainly carried out with traditional zero-valent iron, mainly focusing on reduction dechlorination treatment. Then the application of zero-valent iron gradually developed to surface modification and load modification, and the activity was further strengthened to greatly improve the treatment efficiency of zero-valent iron. After more than ten years of rapid development, with the continuous enhancement of interdisciplinary cross fusion, combined with material functionalization, particle size nano characteristics of the preparation of new zero-valent iron composite materials. Application of zero-valent iron in accordance with local conditions will be an important bottleneck to be broken through in the study of water environmental pollution remediation.
