A novel organic gel film modified electrode was simply and conveniently fabricated by casting Li xMoO y and polypropylene carbonate (PPC) onto the surface of a gold electrode. The cyclic voltammetry and amperometry studies demonstrated that the Li xMoO y 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 3×10-7 to 1×10-4 mol L-1 with a correlation coefficient of 0.9997 and a detection limit of 1×10-7 mol L-1.
