Removal Of Lead Ions Using A Cellulose Acetate/ Zeolite Composite Membrane And Their Analyzes By Inverse Voltammetry

Zeolitic faujasite Y type was prepared from the crystallization of the gel resulting from the combination of the solutions of silica and alumina. Its structure was characterized by XRD, SEM, BET, ATR-FTIR, and elementary analysis. The composite membranes were prepared from a biodegradable polymer “cellulose acetate” serving as a matrix and different percentages of the synthesized faujasite Y. The filtrates obtained were analyzed by inverse voltammetry. The results showed that the retention of lead ions increased with increasing faujasite Y concentrations, and indicated an adsorption capacity of more than 50 % for the lead ions.
