합성 제올라이트를 이용한 pH에 따른 Cu와 Zn 이온의 흡착특성 = Cu and Zn Ions Adsorption Properties at Various pH with a Synthetic Zeolite

다국어 초록 (Multilingual Abstract)

The removal property of Cu and Zn ions by chemical precipitation and adsorption using zeolite (Z-C1) prepared from coal fly ash (CFA) were evaluated in this study. Adsorption kinetic and equilibrium mechanisms described to analyze parameters and correlation factors with Lagergen 1st and 2nd order model and Langmuir and Freundlich model. Analysis of adsorption kinetics data revealed that the pseudo 2nd order kinetics mechanism was predominant. The equilibrium data in pH 3 - 5 were able to be fitted well to a Langmuir model, by which the maximum adsorption capacities(qmax) were determined at 124.9 - 140.1 mg Cu2+/g and 153.2 - 166.9 mg Zn2+/g, respectively. We found that Z-C1 has a potential application as absorbents in metal ion recovery with low pH.
