Preparation of Walnut Shell Based Activated Carbon Using Ilmenite as Pore-forming Agent and Its Adsorption Capability
摘要
Abstract
The activated carbon was prepared using walnut shell as raw material and ilmenite as poreforming agent.The experimental results show that:Under the conditions of zinc chloride concentration 3 mol/L,carbonization time 40 min,carbonization temperature 400℃,ilmenite dosage 5％,the adsorption capacities of the prepared activated carbon for phenol,fuchsine and Pb2+ are 156.80,181.35,35.84 mg/ g respectively,which are more than those of walnut shell based activated carbon by 25.84％,18.59％,19.10％ respectively; Ilmenite used as pore-forming agent can reduce the carbonization temperature and the carbonization time,and promote the mesopore formation of activated carbon,which is favorable to the absorption of macromolecule and heavy metal matters.关键词
