Abstract
An experimental study was carried out on the preparation for activated carbon from bark wastes in wood industry. This study involved an activation test with the phosphoric acid at temperatures in the range of 400 to 900°C, after the bark materials being dried, ground and sorted for sizes smaller than 4 mm.The Parameters, such as internal surface area, pore size distribution and pore volume of the activated product, were measured, and the adsorption capacity with the methylene blue and benzene was tested separately. It was found that for activation longer than 5 minutes, the methylene blue adsorption capacity was increased with an increase in temperature of the above range, while the internal surface area and the benzene adsorption capacity were decreased at the temperatures above 600°C. Besides both trichloroethylene and tetrachloroethylene adsorption tests have shown that activated products of higher adsorption capacity could be obtained with this phosphoric acid activation process as compared with the commercial activated carbon.
