Fabrication of a novel Li(x)MoOy film modified electrode and its application as an electrochemical sensor of iodate.
A novel organic gel film modified electrode was simply and conveniently fabricated by casting Li(x)MoOy and polypropylene carbonate (PPC) onto the surface of a gold electrode. The cyclic voltammetry and amperometry studies demonstrated that the Li(x)MoOy film modified electrode has a high stability and a good electrocatalytic activity for the reduction of iodate. In amperometry, a good linear relationship between the steady current and the concentration of iodate was obtained in the range from 3x10(-7) to 1x10(-4) mol L-1 with a correlation coefficient of 0.9997 and a detection limit of 1x10(-7) mol L-1.
