Preparation of Activated Carbon from Waste Particle Board by Chemical Activation Using Potassium Hydroxide
Abstract:
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.
