Synthesis and characterization of Na-X and Na-A zeolites and adsorption removal of Cu(II) |
| 초록 |
Chronic exposure to high levels of copper can damage the liver and kidneys and may lead to Wilson’s disease, other genetic disorders, and even death. Na-X and Na-A zeolites were synthesized from waste coal fly ash by fusion method. Prepared zeolites such as Na-X and Na-A were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface area analysis and cation exchange capacity (CEC) were investigated. The adsorption removal of Copper (II) by Na-X and Na-A and the adsorption capacity of Cu(II) comparable with commercial zeolites. The adsorption of Copper (II) on zeolites was studied as initial metal concentration, Solution pH, Contact time and ionic strengths. The experimental data of adsorption were interpreted in terms of Freundlich and Langmuir equations and adsorption kinetics data of removal of Copper (II) were studied via pseudo first order and pseudo second order models. |
