Adsorption of Pb2+ ions in aqueous media using the new zeolite nanocomposite adsorbent CaOCdO/ZSM5 synthesized with new techniques

ZSM-5 `is a porous zeolite material that reveals good activity for the adsorption of heavy metals and other contaminants effluent purification. In this scientific research, we synthesized novel CaO-CdO/ZSM-5 nanocomposite adsorbent studied effects different parameters on Pb2+ ions from water media first time. About 99.2% removal efficiency was obtained after contact time 60 min an amount 0.1g/L initial concentration 200mg/L at pH 8 temperature 60oC. The kinetic fit well via pseudo-second-order model. Furthermore, results were reproduced using Langmuir isotherm with maximum capacity mg/g. thermodynamic data displayed over endothermic spontaneous.
