초록

본 연구진이 개발한 적니응집제를 제조하는 과정에서 발생하는 침출슬러지를 재활용하여 중금속이온 제거용 흡착제를 제조하였다. 침출슬러지 10g에 kaolin 1g, sodium silicate solution 2g을 혼합하여 펠

The adsorbent for removal of heavy metal ions is prepared reutilizing the leached sludge generated in process of making the red mud coagulant we have develope. The pellet-type adsorbent is made by heat-treating a mixture of 10g of the leached sludge, 1g of kaolin, and 2g of sodium silicate solution at 600℃ for 2 hours. In experiments of batch adsorption, the adsorbent shows good performance in adsorption of Pb2+ ion.

Keywords:흡착제;적니;중금속;납(Pb2+) 흡착
