Abstract

1:12 Phosphomolybdic acid (PMo₁₂) and graphite powder were homogeneously dispersed into an n-octylpyridinum hexafluorophosphate base carbon ionic liquid electrode (CILE). The cyclic voltammograms of the PMo₁₂ modified CILE showed three well-defined pairs of redox peaks due to the PMo₁₂ system. Formal potentials and electrochemical characteristics including electron transfer rate constant and transfer coefficient were evaluated. Additionally, PMo₁₂modified CILE exhibited good electrocatalytic activity toward iodate reduction. The kinetic of catalytic reduction of iodate on PMo₁₂ modified CILE was investigated in detail. The modified electrode was used for amperometric determination of iodate in commercial table salt.
