Abstract

We report the hydrothermal synthesis of mordenite zeolite in the absence of organic structuring directing agent (OSDA). The mordenite (MOR) zeolite with molar composition 6Na₂O:Al₂O₃:30SiO₂:780H₂O was characterized by XRD, SEM, EDX, and NMR. It was further impregnated with lanthanum and was used in the construction of zeolite modified carbon paste electrode by mixing with different amounts of graphite and paraffin oil to form a paste. The paste composite with the ratio 65:5:30 (graphite:zeolite:paraffin) displayed the best electrochemical behavior in the cyclic voltammetry of K₄Fe(CN)₆ and was hence used for the detection of Cd (II) ions.
