生物质源多孔碳制备及其对废水中药物吸附研究进展

Research progress on preparation of biomass-derived porous carbon and its adsorption of pharmaceuticals in wastewater

城市现代化与工业化的快速发展给环境造成的污染日趋严重,尤其以水体污染最为明显。近年来,工业废水中药物的含量逐年上升,污染程度已经不容忽视。因此,开发新型多孔材料用于废水中药物分子的吸附分离,已经成为了当前的研究热点。综述了近年来生物质源多孔碳(生物炭)在废水中污染物吸附分离方面的研究,首先简单介绍了废水中污染物的治理方法,在此基础上重点探讨了生物炭的制备与修饰,并结合碳材料表面化学性质与孔道结构,总结并展望了生物炭对药物的吸附性能。

The rapid development of urban modernization and industrialization has caused increasingly serious pollution to the environment,especially water contamination.In recent years,the content of pharmaceuticals in industrial wastewater has increased year by year,and the pollution should not be ignored any more.Therefore,the development of new porous materials for the adsorption and separation of pharmaceutical molecules in wastewater has become a current research hotspot.This article summarizes the recent research on the adsorption and separation of pollutants in wastewater by biomass-derived porous carbons(biochars).First,it briefly introduces the treatment methods of pollutants in wastewater,and mainly focuses on the preparation and modification of biochars.Combined with the surface chemical properties and pore structure of the carbon materials,this paper summarizes and prospects the adsorption properties of biochar to pharmaceuticals.
