摘要
Abstract
Using dehydrated sewage sludge and additive composed by sawdust and tar as raw material, a novel granular activated carbon (S-AC) , with highly mesopores and intensity, was prepared by ZnCl2 activation agent. Its structure and characterization were determined by means of BET, FT-IR, etc. , meanwhile, the kinetics of adsorption of three dyes ( Acid red, Neutral red and Basic fuchsin) by SAC was investigated. The results indicated that the BET surface of S-AC was 358 m2/g as well as the intensity was more than 89％. Kinetic analysis suggest that the adsorption rate is mainly governed by film diffusion of Acid red on adsorbent, while the adsorption rate of Neutral red and Basic fuchsin is mainly governed by intra-particle diffusion.关键词
