Abstract

This study examined the removal rate of mixed heavy metals from aqueous solution using recycled aggregate. The recycled aggregate is favorable for the absorbent because it contains about 95% (CaO, $SiO_2$, $Al_2O_3$ and $Fe_2O_3$), which are major ingredient of adsorbent for heavy metal. The kinetic data presented that the slow course of adsorption follows the Pseudo first and second order models. The equilibrium data were well fitted by the Langmuir model and showed the affinity order: $Cu^{2+}$ > $Pb^{2+}$ > $$Zn^{2+}{\simeq_-}Ni^{2+}$$ > $Cd^{2+}$. The results also showed that adsorption rate slightly increased with increasing pH from 6 to 10. Moreover, this trend is similar to results obtained as function of loading amount of recycled aggregate. Meanwhile, an unit adsorption rate was slightly decreased. From these results, it was concluded that the absorbents can be successfully used the removal of the heavy metals from the aqueous solutions.

본 연구에서는 순환골재를 이용하여 수용액상에서 혼합중금속의 제거능을 평가하였다. 순환골재는 주요 성분인 CaO, $SiO_2$, $Al_2O_3$, $Fe_2O_3$가 약 95% 함유되어 흡착제로서 유리한 조성을 가지고 있다. 동적흡착결과를 유사 1차 모델과 유사 2차 모델로 분석한 결과 두 모델 모두 실험결과에 잘 부합하는 것으로 나타났다. 평형흡착 실험은 Langmuir 모델에 잘 부합했고, $Cu^{2+}$ > $Pb^{2+}$ > $$Zn^{2+}{\simeq_-}Ni^{2+}$$ > $Cd^{2+}$순으로 흡착량이 높았다. 용액의 pH가 6에서 10로 증가함에 따라서 흡착률은 증가하는 것으로 나타났다. 또한, 순환골재의 양이 증가함에 따라서 중금속의 흡착률은 증가하였지만, 단위 질량당 흡착량은 감소하였다. 본 연구 결과를 통해 순환골재는 중금속을 효율적으로 제거할 수 있는 흡착제로 판단된다.
