Research Progress on the Adsorption of waterborne Heavy Metal Pollutants by Carbon-based Materials
Heavy metals are highly hazardous pollutants that are difficult to degrade and have a tendency to accumulate in the environment.In recent years,the number of heavy metal pollution incidents has been increasing,posing a serious threat to the ecological environment and human health.Currently,the methods for treating waterborne heavy metal pollution mainly include ion exchange,chemical precipitation,membrane separation,and adsorption.Among them,adsorption methods have been widely used due to their simplicity of operation,wide availability of raw materials,low cost,and recyclability.Carbon-based materials,as porous materials with high surface area,have been extensively studied and considered as ideal adsorbents.This article reviews the recent research progress on various common carbon-based materials in the treatment of heavy metal pollution in water environments and provides an outlook on the future application prospects of adsorption methods in the treatment of heavy metal pollution.
