摘　　要：文章以淀粉为碳前驱体,通过高温热解的方法制备出一种新型的生物质碳材料,XRD表征结果显示,碳材料中的碳以非石墨化的无定型碳的形式存在。结合电镜表征以及N2吸脱附表征,可以得知该碳材料具有优异的比表面积以及独特的孔道结构。同时,以氯酚为水系中的模型污染物,考察该碳材料对其吸附作用,结果表明,该碳材料对水中的氯酚具有优异的吸附作用。这为后续开发具有更加优异吸附作用的碳材料提供了一定的理论和数据支持。In this article,a new type of biomass carbon material is prepared by using starch as carbon precursor through high temperature pyrolysis.XRD characterization results showed that the carbon in the carbon material exists in the form of non-graphitized amorphous carbon.Combined with electron microscope characterization and N 2 adsorption and desorption characterization,it can be known that the carbon material has excellent surface area and unique pore structure.Meanwhile,taking chlorophenol as the model pollutant in water system,the adsorption of chlorophenol by this carbon material was investigated.The results showed that this carbon material had excellent adsorption of chlorophenol in water.It provided some theoretical and data support for the subsequent development of carbon materials with better adsorption.
