【摘要】 土壤电动修复是一种新兴的土壤修复技术。本文以1972-2017年土壤电动修复SCI文献为分析对象,通过定量统计和文本挖掘对过去45年土壤电动修复发展历程和研究态势进行了描述。根据对关键词的整理与分析,发现土壤电动修复研究主要围绕电动修复机理、联合修复技术和场地应用等3个方面,重点修复对象主要是重金属、有机污染物、盐和其他离子以及复合污染物等。开发便捷高效的电动修复场地应用技术将是今后的研究重点之一;电动修复技术与其他修复技术的有机结合、联合修复已成为电动修复研究的热点。更多还原

【Abstract】 Electrokinetic soil remediation( EKSR) is an emerging soil remediation technology. In this study,we took the 1972-2017 EKSR SCI literature as an analysis object and described the EKSR research history of the past 45 years by quantitative statistics and text mining. According to the collation and analysis of the keywords,we found that the research on EKSR mainly focused on three aspects:electric repair mechanism,joint repair technology and field application. The main targets were heavy metals,organic pollutants,salt and other ions and composite pollutants,etc. The development of convenient and efficient electric repair field application technology would be one of the research priorities in the future; the combination of electric repair technology and other repair technologies,joint repair would become a hot spot in electric repair research.更多还原
