Cu and Zn Ions Adsorption Properties at Various pH with a Synthetic Zeolite Lee, Chang-Han;
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 and order model and Langmuir and Freundlich model. Analysis of adsorption kinetics data revealed that the pseudo 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() were determined at 124.9 - 140.1 mg and 153.2 - 166.9 mg , respectively. We found that Z-C1 has a potential application as absorbents in metal ion recovery with low pH.
