Adsorption of Pb2+ Ions Aqueous Environment Using the Novel CaoCdo/Zsm-5 Zeolite Nanocomposite Adsorbent
ZSM-5 is a porous zeolite material that reveals good activity for the adsorption of heavy metals and other contaminants for effluent purification. In this scientific research, we synthesized the novel CaO-CdO/ZSM-5 zeolite nanocomposite adsorbent and studied the effects of different parameters on the adsorption of Pb2+ ions from water media for the first time. About 99.2% adsorption removal efficiency was obtained after contact time of 60 min and adsorbent amount of 0.1 g/L for initial Pb2+ concentration of 200 mg/L at pH8 and temperature of 60o C. The adsorption kinetic fit well via the pseudo-second order model. Furthermore, the adsorption results were reproduced using the Langmuir isotherm with a maximum adsorption capacity of mg/g. The thermodynamic data displayed that the adsorption of Pb2+ ions over the CaO-CdO/ZSM-5 nanocomposite were endothermic and spontaneous.
