Cyclic voltammograms of the bare glassy carbon electrode (a). The scan rates were 0.025, 0.050, 0.075, 0.100, 0.125, 0.150, and 0.200 V/s. Relationship between the scan rate and the reduction and oxidation peak current of the pretreated glassy carbon electrode (b). The scan rates were 0.025, 0.050, 0.075, 0.100, 0.125, 0.150, and 0.200 V/s, and the correlation coefficients of Epa and Epc are 0.9993 and 0.9968.
