摘要：将活性污泥和面粉共混、发酵、烤制,经KOH浸渍、1000℃下制备得到炭化物.采用比表面孔径测试仪(BET)和扫描电镜(SEM)对其表面结构和形貌进行了表征,利用紫外可见分光光度计(UV)对炭化物吸附性能进行了分析.结果表明:(1)所制备的炭化物呈现不规则的多重孔结构;(2) KOH处理后的炭孔容达到0.43cm^3/g,比表面积提高到648.2 m^2/g;(3)当吸附达到平衡时,炭化物对染料的去除率超过90%.
A novel carbon from activated sludge modified by flour was prepared.The preparation process includes mixing,fermenting,baking,KOH impregnation and carbonization at 1000℃.Specific surface area and morphology of carbon were characterized by specific surface area,pore size analyzer(BET)and Scanning Electron Microscope(SEM),and the adsorption property was explored by UV-visible spectrophotometer(UV).The results are as follows:(1)the carbon with irregular multi-model hierarchical porosity has numerous pores;(2)after KOH activation,the pore volume and the specific surface area of carbon are up to 0.43 cm 3/g and 648.2 m 2/g,respectively;(3)dye removal efficiency of the carbon is above 90%.
