Abstract:
Column-shaped activated carbon was prepared using carboxymethyl cellulose (CMC) as adhesives. Effects of experimental parameters including carbonization temperature and the amount of CMC on the adsorptive capacity, pore structure, and strength of product were investigated. The results showed that specific surface area (SBET), adsorption capacity of methylene blue and iodine decreased with carbonization temperature increasing. It was also found SBET, total pore volume, micropore volume, average pore size, adsorption capacity of methylene blue, iodine and toluene of product decreased with the increased amount of CMC, while the strength of product increased. Optimum conditions were determined as follows: carbonization temperature 200 ℃ and amount of CMC 10 %. SBET of product prepared under this condition can achieve 844.9 m2/g, adsorption capacity of methylene blue and iodine were 189.2 and 968.2 mg/g, respectively strength achieved 99.83 %, adsorption capacity of toluene was 65.5 %.
