The electrochemical properties of 12-molybdophosphoric acid modified ionic liquid carbon paste electrode

A [C₈mim]₃PMo₁₂O₄₀-modified ionic liquid carbon paste electrode ([C₈mim]₃PMo₁₂O₄₀-ILCPE, C₈mim = 1-methyl-3-octylimidazolium) was successfully fabricated. Its electrochemical properties were carried out on the cyclic voltammograms. The results of the cyclic voltammograms indicated that [C₈mim]₃PMo₁₂O₄₀-ILCPE exhibited remarkable electrocatalytic activities toward the reduction of BrO₃^- and good stability. The value of I_pc was as a function with the concentration of bromate from 2 × 10^-6 to 1 × 10^-4 M, which indicated that the [C₈mim]₃PMo₁₂O₄₀-ILCPE can be a candidate for electrochemical sensor.
