英文摘要	应用循环伏安法、线性电位扫描法研究盐酸吡哆辛(VB6)在聚溴甲酚绿修饰电极上的电化学特性.在pH=4 HAc-NaAc缓冲溶液,0.7~1.2 V电位区间,盐酸吡哆辛在聚溴甲酚绿电极有一不可逆氧化峰(0.978 V),转移电子数n为1,质子数m为1,传递系数α为0.37.VB6氧化峰电流与其浓度1×10-3~2×10-5mol/L范围内呈线性关系,相关系数0.9967,样品加标平均回收率为100.06%,检出下限为2×10-6mol/L.; 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%.; 作者联系地址：西华师范大学化学化工学院应用化学与污染技术四川省重点实验室;; Author's Address: College of Chemistry and Chemical Engineering,China West Normal University;Laboratory of Applied Chemistry and Pollution Control Technology,Nanchong 637002,Sichuan,China
