배추를 이용한 활성탄 제조에 관한 연구 = Study on the Production of Activated Carbon using Chinese Cabbage

다국어 초록 (Multilingual Abstract)

In recent years, the demand of activated carbon has been increasing steadily because of the environmental problems. Among them waste and water treatment and removal of poisonous gas were involved. Therefore, in this study, activated carbon was made from the waste chinese cabbage and measured the iodine adsorption ability, carbonization yield, and activation yield of the produced activated carbon. The result showed that the carbonization yield was decreased when carbonization temperature was increased and that the optimal carbonization temperature was 600℃. The optimal concentration of NaOH for removing ash in the raw sample was 1∼2N. The range of iodine adsorption number of activated carbon using chinese cabbage at 600℃ carbonization was 610.82㎎/g to 1019.58㎎/g. The activation result of carbonization sample showed that the optimal activation condition was the carbonization at 400℃ and the activation at 700℃. So the production of activated carbon using chinese cabbage was possible in the aspect of reuse of resource and decrease of environmental pollution compared to the commercial activated carbon.
