Abstract

In this study, the heavy metal ions (of Pb, Cd, Cr, and Hg) in wastewater were removed using a spent Li₂O-Al₂O₃-SiO₂-based crystallized glass previously used as an induction top plate material. Changes in the removal efficiency of heavy metals according to different reaction parameters, such as the amount of zeolite used as a heavy-metal adsorbent, adsorption time, initial concentration of the heavy metals, and pH of the initial solution, were investigated. As the amount of zeolite added increased, the heavy-metal removal efficiency also increased. Adsorption time had a considerable influence on adsorption characteristics, and the removal efficiency of all heavy metals increased with increasing adsorption time. In the case of Cd, the removal efficiency was greatly improved depending on the adsorption time. The initial concentration of the heavy-metal solution did not affect the removal efficiency; however, the initial pH of the heavy-metal solution affected the removal efficiency. More specifically, the removal efficiency of Cd increased while that of Pb and Cr decreased with increasing pH. The adsorption characteristics of Hg were not significantly affected by pH.

본 연구에서는 인덕션 탑플레이트(induction top plate) 소재로 사용된 후 폐기되는 사용 후 Li₂O-Al₂O₃-SiO₂계 결정화 유리를 활용하여 중금속 용액 내 존재하는 중금속(Pb, Cd, Cr⁶⁺, Hg) 이온들의 제거 실험을 진행하였다. 중금속 흡착제로 사용된 흡착제의 양, 흡착 반응시간, 초기 중금속 원소의 농도, 초기 용액의 pH 등의 반응 조건에 따른 중금속 제거 효율의 변화를 조사하였다. 사용 후 LAS 첨가량이 증가할수록 중금속 제거 효율이 상승하였다. 흡착 반응 시간은 흡착 특성에 큰 영향을 미치는 것으로 확인되었으며, 모든 중금속 원소들의 제거 효율이 상승하였다. 특히 반응 시간에 따라서 Cd의 경우 흡착제거 효율이 크게 개선되었다. 초기 중금속 용액 농도는 중금속 제거 효율에 영향을 미치지 않았다. 중금속 용액의 pH는 중금속 제거 효율에 영향을 미쳤는데, Cd의 경우 pH증가에 따라 중금속 제거 효율이 증가하였으며, Pb, Cr⁶⁺는 감소하였다. Hg는 pH가 흡착 특성에 큰 영향을 미치지 않았다.
