This research was performed to investigate the utilization of fly ash as an adsorbent for effective disposal by recycling of fly ash generated from power plant. The adsorption characteristics of this adsorbent was also studied through the analysis of specific surface area, the adsorption of iodine and heavy metal ions, and the removal efficiency of COD.The iodine adsorption of the adsorbent added to 10% Na2SO4 at 800 was as high as 355mg/g, and the specific surface area of the adsorbent was about 2.5∼4.0m2/g, which was 8∼13 times higher than fly ash. The adsorption of activated charcoal and the manufactured adsorbent at 500 Pb2+mg/L at pH 3 were 5.29mg/g and 46.5mg/g, respectively. The removal efficiency of the manufactured adsorbent was about 8.8 times as high as that of activated charcoal, but it was lower for Cu and Cd than activated charcoal. The COD removal efficiency of the manufactured adsorbent added to 30% Na2SO4 at 800 was 90%.
