氯化锌活化生物质炭制备活性炭及其表征
Preparation and characterization of activated carbon from bio-char by chemical activation with ZnCl2
摘要
Abstract
High surface area activated carbons were prepared with bio-char as raw material and ZnCl2 as activating agent. Effects of impregnation ratio,activator concentration,activation temperature,and activation time on the adsorptive capacity of activated carbon were studied. The properties and pore structure of the carbon were characterized with nitrogen adsorption-desorption,scanning electron microscopy (SEM),infrared spectroscopy (FT-IR),power X-ray diffractometry (XRD). The suitable preparation condition was obtained as follows:impregnation ratio of 3,activator concentration of 40%, activation temperature of 600℃and activation time of 90min. The results show that the methylene blue adsorption on activated carbon,which was obtained under above condition,reaches to 213mg/g,which was much higher than the national first level for activated carbon. The activated carbon has a large apparent surface area (SBET=631.2m2/g),relatively concentrated pore (2nm pore is more than 84.4%) and high adsorption power volume (V=0.352cm3/g).关键词
