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

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.
