Production of activated Carbon for Utilization of Bark from Russian Wood

An experimental study was carried out on the peparation for activated carbon with zinc chloride, phosphoric acid and alkari hydroxide from bark wastes in wood industry. Parameters such as internal surface area, pore size distribution and pore volume of the activated product were measured and the adsorptive capacity with methylene blue, benzene trichloroethylene tetrachloroethylene was tested. The tests showed that activated products which could be obtained with chemical reagents activation process have more adsorptive capacity than the commercial activated carbon.
