Abstract
Heavy metal adsorption on peat was studied to examine the utilization of abundant natural resouces as pollution control. The smaller the peat particle size, the more the heavy metals studied were adsorbed. Adsorption of heavy metals on peat was greater in single metal solutions than in mixed solutions, and the order of adsorption amount on peat was Cu > Cd > Zn. The most effective pH range of the adsorption of Cd, Zn, and Cu was between 4 and 6. With increasing the concentration of heavy metals the amount of adsorption on peat was increased, but the adsorption ratio was decreased. The adsorption of heavy metals on peat was fitted to the Freundlich isotherm and peat was appeared to be an effective adsorbent of the heavy metals. The treatment of polyethyleneimine(PEI) on the peat surface effectively increased adsorption capacity of the heavy metals. Because of its higher energy content, the heavy metal adsorbed peat could be utilized as a energy source. After burning the peat, the reduced peat volume could be save the expenses for waste disposal.
