摘　　要：石墨烯材料具有较大的比表面积、良好的化学稳定性,近年来在环境污染物深度吸附处理方面的应用逐渐引起了人们的关注。本文综述了石墨烯材料在重金属离子的吸附处理方面的研究进展,包括普通石墨烯、氧化石墨烯、功能化石墨烯以及石墨烯复合物等材料;讨论了石墨烯表面功能化修饰对重金属离子吸附性能的影响;分析了各种材料的优点与缺点;提出了需进一步研究的问题,如石墨烯表面功能化修饰的结构-性能关系、石墨烯材料的循环使用以及石墨烯材料对痕量重金属离子的富集灵敏度等问题,指出合成选择性好、富集灵敏度高且可多次循环使用的石墨烯材料,在重金属废水的深度处理中将得到进一步应用。Graphene based materials have large specific surface area and good chemical stability. In recent years,grapheme based materials are widely used for the deep adsorption of environmental pollutants in different samples and have received great attentions by researchers. In this paper,the recent progress for the adsorption of heavy metals by grapheme based materials was reviewed,including pristine graphene,grapheme oxide,functionalized grapheme and grapheme based composite. The influences on the metal ions adsorption property by functionalized graphene were discussed. The advantages and disadvantages of the materials for the adsorption of heavy metals were also analyzed. The future development in this area was proposed,such as the relationship between structure and property,the reusability of the material and the adsorption sensitivity for heavy metals at trace level. Several important issues are suggested for the future work,i.e. the synthesis of materials with high selectivity,sensitivity and reusability for the adsorption of heavy metal ions in waste water treatment.
