(a) Cyclic voltammograms of 50 μg L−1 Co(II)DMG complex using Bi modified CSPE with different scan rates (40–90 mV s−1). The expansion of reduction peaks of Co(II)DMG is shown in inset. (b) Relationship between peak current and square root of scan rate from (a) (n=3). (c) Cyclic voltammograms of 50 μg L−1 Ni(II)DMG complex using Bi modified CSPE with different scan rates (40–90 mV s−1). The expansion of reduction peaks of Ni(II)DMG is shown in inset. (d) Relationship between peak current and square root of scan rate from (c) (n=3).
