Abstract
The adsorption ability of charcoal made from waste wood was evaluated in order to determine whether the charcoal could be utilized as an adsorbent for water treatment. The iodine adsorption capacity, the MB decolorization capacity, the ABS value and the phenol value of charcoals that were produced from waste wood under different conditions were evaluated. As the specific surface area of the charcoal increased, both the iodine adsorption capacity and the MB decolorization capacity increased, while the ABS and phenol values decreased. The adsorption ability of the charcoal increased as the surface area of the charcoal increased. The highest adsorption ability of the charcoals made from waste wood is almost the same as that of activated carbon available on the market.
Pond water purification tests were carried out with waste wood charcoal and with activated carbon that is available on the market. The ability of the charcoal to lower COD and the color unit of the water was higher than that of the activated carbon.
