英文摘要	采用电化学聚合法制备了聚铬黑T膜修饰电极，应用扫描电镜、交流阻抗法和循环伏安法对修饰电极进行表征，以循环伏安法研究硫酸特布他林在修饰电极上的电化学行为，并以差示脉冲伏安法对其含量进行测定.该方法对硫酸特布他林有明显的电催化作用，在pH 7.0磷酸盐缓冲液中，氧化峰电流与硫酸特布他林浓度在1.2x10-7~2.0x10-6 mol•L-1范围内呈良好的线性关系，检测限为1.5x10-8 mol•L-1，回收率在97.9%～104.6%之间，RSD在2.8 % (C=8x10-7 mol•L-1，n=11).该方法简便灵敏，结果准确可靠，方法重复性好，可用于硫酸特布他林及其片剂的质量控制.; The poly eriochrome black T modified electrode was prepared by electropolymerization. This modified electrode was characterized by scanning electron microscopy(SEM), electrochemical impedance spectroscopy(EIS) and cyclic voltammetry (CV). The electrochemical behaviors of terbutaline sulfate were studied by CV, while the recoveries were measured by differential pulse voltammetry (DPV). The modified electrode shows excellent electrocatalytic characteristics for terbutaline sulfate. In pH 7.0 phosphate buffer solution, the oxidation peak currents obtained by DPV were linear to the terbutaline sulfate concentrations over the range of 1.2x10-7~2.0x10-6 mol•L-1. The detection limit was estimated to be 1.5x10-8 mol•L-1 and the average recovery was 97.9%～104.6%. The relative standard deviation (RSD) was 2.8% for 8x10-7mol•L-1terbutaline sulfate (n=11). This method is simple, sensitive, and accurate with good repeatability, and can be used for the determination of terbutaline sulfate and the corresponding tablets.; 国家863计划项目（2012AA022604）；国家自然科学基金（81171668，21405015 ）；福建省教育厅科技A类项目（JA13147）；大学生创新创业训练计划项目（201410392034，201510392099）资助.; 作者联系地址：1. 福建医科大学药学院药物分析系, 福建福州 350108; 2. 福建省高等学校纳米医药技术重点实验室，福建福州 350108; Author's Address: 1.
