摘要:

将香烟过滤嘴在低温和氩气气氛中烧结制得碳材料(记为CFC),采用X-射线衍射(XRD)、扫描电子显微镜(SEM)、比表面积测定等手段对CFC的结构和表面形貌进行表征.将CFC作为废水中亚甲基蓝(记为MB)的吸附剂,采用单因素法研究废水pH值、CFC投加量、MB初始质量浓度、吸附时间、吸附温度等对MB吸附效果的影响规律.结果表明,CFC由多孔的无定形碳颗粒组成,其比表面积高达1 648 m/g,总孔容达到0.815 cm/g.最佳吸附工艺条件:pH值9.0,CFC投加量0.3 g/L,MB的初始质量浓度140 mg/L,吸附时间180 min,吸附温度35 ℃.在此条件下,CFC对MB的吸附率达到93.44%,吸附量达到360.06 mg/g,说明利用CFC可有效去除废水中MB.

Abstract:

Carbon materials derived from used cigarette filters(CFC) was prepared by calcinating the used cigarette filters at low temperature and in presence of Ar.X-ray diffraction (XRD),scanning electron microscopy (SEM) and specific surface area measurements were used to characterize the microstructure,pore morphology and surface properties of CFC.The effects of pH of MB solution,adsorbent dose,initial concentration of MB,contact time and reaction temperature on the adsorption of MB were investigated in detail.Results show that the as prepared CFC is composed of porous amorphous carbon with a specific surface area of 1 648 m/g and total pore volume of 0.815 cm/g.The optimal adsorption process was obtained as follows:pH is 9,CFC dose is 0.3 g/L,initial concentration of MB is 140 mg/L,contact time is 180 min and reaction temperature is 35 ℃.Under this condition,the MB removal rate is more than 93.44% and the adsorption capacity of CFC is more than 360.06 mg/g,suggesting CFC derived from used cigarette filters is a good adsorbent for MB.
