中文摘要：
制备多壁碳纳米管修饰玻碳电极,应用循环伏安法研究沙丁胺醇在修饰电极上的电化学行为。结果表明,碳纳米管修饰电极对沙丁胺醇的氧化有良好的电催化活性,在最佳测试条件下,氧化峰电位负移至0.601V,比裸玻碳电极负移90mV,氧化峰电流与沙丁胺醇浓度在2.09×10^-7～2.27×10^-6mol/L范围内呈良好线性关系,检出限达1.9×10^-7mol/L。该电极具有良好的重现性和稳定性。
英文摘要：
A glassy carbon electrode modified by functionalized multi-wall carbon nanotubes （MWCNTs-COOH） film was prepared. Electrochemical behaviors ofsalbutamol on the modified electrode were investigated by cyclic voltammetric （CV） method. Results indicated that the modified electrode with MWCNTs-COOH film exhibited an excellent electro-catalysis activity to salbutamol oxidation. All experimental parameters were optimized and the oxidation peak potential of salbutamol at the modified electrode was negatively shifted to 0.601 V under the optimal conditions, which also exhibited a negative shift approximately 90 mV compared to the naked grassy carbon electrode. An excellent linear relationship between oxidation peak current and salbutamol concentration in the range from 2.09 × 10^-7 to 2.27 × 10^-6 mol/L was observed. The detection limit was approximately 1.9 × 10^7 mol/L. Moreover, this electrode revealed excellent reproducibility and stability.
