초록

스코리아와 활성탄의 혼합 충전탑에서 중금속과 유기물의 흡착 특성, 스코리아의 물리화학적 특성과 관능기를 조사하였다. 스코리아의 혼합비율이 증가할수록 카드뮴, 니켈, 크롬, 납 이온의 평균제거율은 증가하였으나, 벤젠과 톨루엔의 평균 제거율은 감소하였다. 스코리아와 활성탄의 혼합 충전탑은 중금속과 유기물의 동시 제거에 효과적으로 사용될 수 있었다. 스코리아는 Si-H와 Si-O 작용기를 갖고 있으며, 이중 Si-O 관능기가 중금속의 흡착에 크게 기여함을 확인할 수 있었다.

Adsorption properties of heavy metals and organics in the mixed packed column of scoria and activated carbon, as well as physicochemical properties and functional groups of scoria were investigated. As the mixing ratio of scoria increased, the average removal ratios of cadmium, nickel, chromium, and lead ions increased, but that of benzene and toluene decreased. The mixed packed column of scoria and activated carbon could be effectively used for the simultaneous removal of heavy metals and organics. Scoria has Si-H and Si-O functional groups, and it was confirmed that Si-O functional groups greatly contributed to the adsorption of heavy metals.
