산업부산물을 이용한 중금속 제거효율에 관한 연구
초록
Environmental pollution problems due to the wastes from various industrial facilities and activities have become a serious issue. The specific problem associated with heavy metals in the environment is their accumulation in the food chain and their persistence in nature. Present work investigates the possible uses of by-products for the removal of heavy metal ions. Heavy metals used in these studies were cadmium, lead and copper. Experiments were conducted with by-products such as oyster shell and fly ash to evaluate their sorption characteristics. The results of the study indicate that oyster shell can be properly used as an adsorbent for heavy metals because of its outstanding removal rate.
