中文摘要：

以pH=2.0的0.04 mmol/L BR缓冲液为支持电解质,玻碳电极为工作电极,分别采用循环伏安法(cyclic voltammetry,CV)、线性扫描伏安法(linear sweep voltammetry,LSV)和微分脉冲伏安法(differential pulse voltammetry,DPV)等技术对玻碳电极(glassy carbon elecbrode,GCE)上美雄酮的电化学行为进行研究,并选定微分脉冲伏安法进行定量分析.美雄酮在-0.932 V(vs.SCE)处有一阴极还原峰,其峰电流与美雄酮样品浓度在2.0～60.0μmol/L范围内呈良好的线性关系,其最低检测限(D=2σ/K)为0.43μmol/L.该方法已成功地用于大力补药片和尿样中美雄酮的分析检测.并探讨了美雄酮在玻碳电极上的电极反应机理,该反应属于得到1个质子和2个电子的不可逆的还原反应.本研究为开发便携式实时兴奋剂检测器奠定基础.

英文摘要：

Electrochemistry behaviour of methandienone on glassy carbon electrode was studied in this paper.Based on the voltammetric behaviour research results,it promises to develop a new portable electrochemical sensor for the real-time detection of doping.The electrochemical response of methandienone in 0.04 mmol/L BR buffer solution(pH=2.0) was investigated by cyclic voltammetry,linear sweep voltammetry and differential pulse voltammetry(DVP) methods,of which DPV was chosen as the method of quantitive analysis.Th...
