摘要:

重金属是矿山废水中的主要污染物。重金属污染治理方法中吸附法被广泛研究和应用。磁性氧化石墨烯(mGO)纳米复合材料具有合成工艺简单、成本低、吸附效率高、稳定性好、易于和重金属分离并可重复利用等优点,是一种较为理想的吸附材料。结合近年来的研究成果,综述了mGO的制备、表征,以及其吸附重金属的影响因素、吸附机理等,并对未来研究方向提出了展望。

Abstract:

Heavy metals are the main pollutants in mine wastewater. Adsorption method is widely studied and used in heavy metals pollution treatment. Magnetic graphene oxide(mGO) nanocomposites have many advantages, such as simple synthesis process, low cost, high adsorption efficiency, good stability, easy separation from heavy metals and reuse, and so on, which is an ideal adsorption material. In this paper, the preparation and characterization of mGO, the adsorption influencing factors and the adsorption mechanism of heavy metals are reviewed. The future research direction is also prospected.

Key words: magnetic graphene oxide, nanocomposite, adsorption, water treatment, heavy metals
