Abstract

Abstract: A procedure was described where an 13X-type zeolite film could be formed on a glassy carbon electrode. Using cyclic voltammetry, we surveyed the electroresponses of H₂Q/Q redox couple at the modified electrode thus formed. The stable cyclic voltammograms were obtained rapidly, and were not altered when the temperature of the solutions was changed or the solutions were stirred, but they were effected by the solutions'pH values. It was observed that both the oxidation of H₂Q and the reduction of Qwere catalyzed by the modified electrode when pH≤2.0.

Key words: Zeolite, Modified electrode, H₂Q/Q redox couple
