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

摘要

A [C_8mim]_3PMo_(12)O_(40)-modified ionic liquid carbon paste electrode ([C_8mim]_3PMo_(12)O_(40)-ILCPE, C_8mim = 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 [C_8mim]_3PMo_(12)O_(40)-ILCPE exhibited remarkable electrocatalytic activities toward the reduction of BrO_3~- 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 [C_8mim]_3PMo_(12)O_(40)-ILCPE can be a candidate for electrochemical sensor.
