Abstract

Electrochemical characteristics of VB6 were investigated at PBG modified electrode by Cyclic voltammetry and linear sweep voltammetry.The VB6 produced an irreversible oxidation peak at 0.978 V(Vs.SCE) in HAc-NaAc(pH=4.0) buffer solution over the potential range of 0.7 to 1.2 V.The electron number,the proton number,the transfer coefficient were determined to be 1,1 and 0.37,respectively.The oxidation peak currents of VB6 versus its concentration showed a linear relationship in the concentration range of 1×10-3~2×10-5mol/L with the correlation coefficient of 0.9967 and the detection limit of 2×10-6mol/L.The recovery was 100.06%.
