At Hcy/Au electrode, there were electrocatalytic responses of DA and E with ΔEp 57.5mV and 63.5mV, respectively. The standard rate constants k〓 were calculated as 2.1×10〓 cm s〓 and 1.6×10〓 cm s〓 corresponding to DA and E. The electron transfer number n〓=1 was achieved, which revealed that the 2e transfer of DA and E is not completed by one step at the electrode. Because AA also displayed electrocatalytic behavior at Hcy/Au electrode, DA and E can be determined in presence of AA.At Hcy/Au electrode, a pair of very stable and well-defined redox waves of Mb were obtained.
