The objective of this research was to develop the adsorbent for heavy metals by activating the bark sample. Barks from pine tree with diameters of 2~4 mm were activated in the muffle furnace under a high relative humidity condition at temperatures of 600~900℃. The removal efficiency of the activated bark (ACTBARK) for Cu and Cd was temperature dependent showing the order of 900℃, greater than 800℃ greater than 700℃, greater than 600℃. The critical temperature was considered to be 900℃ to become an efficient adsorbent for Cu and Cd.
