Carbon-based nanomaterials, especially carbon nanotubes and graphene, have drawn wide attention in recent years as novel materials for environmental applications. Notably, the functionalized derivatives of carbon nanotubes and graphene with high surface area and adsorption sites are proposed to remove heavy metals via adsorption, addressing the pressing pollution of heavy metal. This critical revies assesses the recent development of various functionalized carbon nanotubes and graphene that are used to remove heavy metals from contaminated water, including the preparation and characterization methods of functionalized carbon nanotubes and graphene, their applications for heavy metal adsorption, effects of water chemistry on the adsorption capacity, and decontamination mechanism. Future research directions have also been proposed with the goal of further improving their adsorption performance, the feasibility of industrial applications, and better simulating adsorption mechanisms.
近年来，碳基纳米材料（特别是碳纳米管和石墨烯）作为环境应用的新型材料引起了广泛关注。值得注意的是，具有高表面积和吸附位点的碳纳米管和石墨烯的功能化衍生物被提议通过吸附去除重金属，以解决重金属的紧迫污染问题。本综述评估了各种功能化碳纳米管和石墨烯用于去除受污染水中重金属的最新发展，包括功能化碳纳米管和石墨烯的制备和表征方法、它们在重金属吸附方面的应用、水化学对吸附能力的影响以及去污机制。还提出了未来的研究方向，目的是进一步提高它们的吸附性能、工业应用的可行性以及更好地模拟吸附机制。
