Research progress on removal of chlorinated organic compounds using iron-carbon composite materials

铁碳(Fe-C)复合材料可应用于污染场地中COCs的去除。综述了近年来Fe-C复合材料的制备方法(包括液相还原法、碳热还原法、水热碳化法、球磨法和绿色合成法),总结了几种常见碳材料载体(包括活性炭、生物炭、碳纳米管和石墨烯)的优缺点,梳理了Fe-C复合材料与COCs的相互作用机制(包括吸附、还原脱氯和刺激微生物脱氯),并对该领域未来的发展方向进行了展望,为Fe-C复合材料用于实际COCs污染场地的修复提供参考。

Iron-carbon(Fe-C)composite materials can be applied to remove COCs from contaminated sites.The preparation methods of Fe-C composite materials in recent years are reviewed,including liquid phase reduction,carbothermal reduction,hydrothermal carbonization,ball milling and green synthesis.The advantages and disadvantages of several common carbon material carriers(including activated carbon,biochar,carbon nanotube and graphene)are summarized.The interaction mechanisms between Fe-C composite materials and COCs are reviewed,such as adsorption,reduction dechlorination and stimulation of microbial dechlorination.The future development direction of this field is prospected,providing a reference for the application of Fe-C composite materials in the remediation of actual COCs contaminated sites.
