【摘要】 就重金属污染土壤电动修复的行为机制、研究进展和实际应用等进行了综述。土壤电动修复是指在污染土壤上施加直流电压导致土壤中的污染物质在电场作用下进行电迁移、电渗流、电泳等过程通过电场,并在电极附近由溶液导出并进行适当的物理或化学处理,实现污染土壤的清洁。该技术具有所用化学试剂少、能耗低、修复彻底等优点,是一门具有较好发展前途的绿色修复技术,目前已引起环境科学家们广泛的关注。更多还原

【Abstract】 Electrokinetic remediation is an emerging technology to clean up polluted soil. It applies a low DC potential difference on soil, and contaminants come from soil into electrolyte by electromigration, electroosmosis and electrophoresis. The electrolyte is then treated by physical and chemical methods. Its advantages include less chemicals needed, low energy consumed and clean thoroughly. So, this is a green remediation technology and attracts the attention of many environmental scientists. This paper reviews electrokinetic remediation of heavy metal contaminated soil, including its mechanism, progress and application in practice.更多还原
