Abstract

Mordenite zeolite with an average size of 17 µm was synthesized hydrothermally from the gel composition of 9.4 Na₂O: Al₂O₃:40 SiO₂:1040 H₂O in the absence of organic structure directing agent (OSDA) and without seed addition. The crystallinity, elemental composition, and morphology of the mordenite crystals were confirmed by XRD, EDS and FE-SEM, respectively. The impregnation with phosphate of the synthesized mordenite was achieved by suspending it in aqueous solution of 5 wt.% H₃PO₄. The effect of the phosphorus impregnation was studied using solid-state NMR. The electrochemical behavior of phosphate mordenite zeolite was investigated in carbon paste via cyclic voltammetry. The optimized composite electrode was used for detection of thiocyanate ions.
