Abstract
In this study, a polyvinyl chloride (PVC) membrane impregnated with the zeolite ZSM-5 was used to remove Fe2+ and Cu2+ ions from aqueous solutions. The results obtained by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analyzes indicated that the zeolite produced by the hydrothermal method was a pure porous material. The prepared zeolite was then incorporated into the PVC to obtain composite films which behave as filters. These composite membranes were used for the removal of metal ions contained in aqueous solutions. The filtrates obtained were analyzed by atomic absorption spectroscopy. The results showed the existence of a selective retention of metal ions according to their ionic radii. It increases with the ionic radii (RFe: 55 μm, RCu: 73 μm), and which increased in general with the concentration of the ZSM-5 zeolite .
