Preparation and Characterization of Activated Carbon from Rice Husk with Composite Activator
摘要
Abstract
A range of activated carbons were prepared from rice husk with ZnCl2-CuCl2 composite activator. The preparation conditions were optimized by orthogonal test using ZnCl2 concentration,CuCl2 concentration,activation temperature and activation time as effect factors. The adsorption properties of produced activated carbons were investigated. Rice husk-based activated carbon (RAC) was characterized by nitrogen adsorption-desorption isotherms and X-ray diffraction (XRD). Results indicated that rice husk could produce activated carbon with high surface area. The optimized conditions were as follows:5mol/L ZnCl2 ,0. 4 mol/L CuCl2 ,activation temperature 500℃,and activation time 2 h. The Iodine number,methylene blue value and BET surface area of the prepared activated carbon were 1 041 mg/g,188 mg/g and 1 924 m2/g,respectively.关键词
