Cyclic voltammograms of 1.0 mM DP in buffer solution of pH 4.2 (I = 0.2 M) at scan rates of (a) blank, (b) 0.006, (c) 0.02, (d) 0.03, (e) 0.05, (f) 0.07, (g) 0.09, and (h) 0.1 Vs−1. A Dependence of peak current I p/μA on the scan rate υ/Vs−1. B Plot of logarithm of peak current log I p/μA versus logarithm of scan rate log υ/Vs−1. C Plot of variation of peak potential E p/V with logarithm of scan rate log υ/Vs−1
