摘　　要：制备出多壁纳米管修饰玻碳电极,研究了特布他林在该修饰电极上的直接电化学行为。实验结果表明,特布他林在该修饰电极上具有良好的电流响应。采用示差脉冲伏安法测定特布他林,其氧化峰电流与浓度在1.0×10-6～5.0×10-4mol/L范围呈良好线性关系,线性方程为:ip(μA)=0.2263+0.3307c(μmol/L),相关系数r=0.9949。检测限为1×10-7mol/L(信噪比为3)。该电极用于特布他林片剂中特布他林的含量测定,结果令人满意。A multi-wall nanotube modifying glassy carbon （GC） electrode has been fabricated and showed potent electrocatalytic activity toward the electrochemical oxidation of terbutaline in phosphate buffer solution （pH 7.4）. The linear dependence between the oxidation peak height of terbutaline and its concentration was observed in the range from 1.0×10^-6 to 5.0×10^-4 tool/L with a detection limit of 1.0×10^-7 mol/L （at a S/N=3）. The determinations of terbutaline in tablets were carried out and satisfactory results were obtained.
