Preparation of Activated Carbon from Waste Particle Board by Chemical Activation Using Potassium Hydroxide
Activated carbons were prepared through chemical activation of waste particle board (WPB) precursor using potassium hydroxide as the chemical agent. The effects of different parameters, such as chemical/WPB ratio, activation time and activation temperature on yield and the methylene blue adsorption capacity of activated carbon were investigated. Experimental results indicated that the optimum conditions were as follow: activation temperature 850°C, KOH(50% concentration)/ WPB 4.0, activation time 50 min. Amount of methylene blue adsorption, Iodine number and the yield of activated carbon prepared under optimum conditions were 15.0 mL/0.lg, 1213mg/g and 36.9%, respectively. Therefore, great potential exists for developing activated carbon products from waste wood, which will have the positive effects of reducing our landfill problem and gain attractive products.
