摘　　要：柚子皮在450℃下焙烧,制得生物活性炭,经红外光谱(FTIR),扫描电子显微镜(SEM)表征,结果表明,柚子皮生物活性炭中含有游离的羟基、硝基化合物和酸酐集团,表面不平整,呈片状结构,有丰富的孔隙。生物活性炭投加量8 g/L时,吸附时间16 h,饱和吸附量为187μg/g,对芘污染物去除率为37%。吸附过程符合Langmiur模型。Biological activated carbon was prepared by roasting grapefruit skin at 450℃.The infrared spectroscopy(FTIR)and scanning electron microscopy(SEM)showed that the grapefruit skin biochar contained free hydroxyl groups,nitro compounds and anhydrides group,the surface is uneven and has a sheet-like structure with abundant pores.When the dosage of biological activated carbon was 8 g/L,the adsorption amount was 187μg/g at 16 h,and the pyrene contaminant removal rate was 37%.The adsorption process is in accordance with the Langmiur model.
