doi:DOI:10.3969/j.cnki.jdxb.2017.01.015

Abstract

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.
