| 中文摘要采用电化学阻抗法、循环伏安法、计时电量法、差分脉冲伏安法等分析手段,研究了硫酸特布他林在石墨烯修饰玻碳电极( GR / GC) 上的电化学行为及电化学动力学性质,建立了硫酸特布他林电化学定量测定方法。 实验结果表明,硫酸特布他林在 GR / GC 电极上的电化学过程是一个不可逆电化学氧化过程,氧化过程受扩散控制,在扫描速度 20 ~ 250 mV / s 范围内,其氧化峰电流与扫描速度平方根呈良好的线性关系。 该方法可简便、快捷、灵敏地检测博利康尼中硫酸特布他林的含量。 |
| 英文摘要: |
| The electrochemical behaviors and electrochemical kinetics of terbutaline sulfate on graphene modified glassy carbon electrode ( GR / GC) were studied and a novel electrochemical quantitative analysis for the determination of the concentration of terbutaline sulfate was establish by using electrochemical impedance spectroscopy, cyclic voltammetry, chronocoulometry, differential impulsive voltammetry and other methods. The results indicated that the electrochemical process of terbutaline sulfate on GR / GC electrode was an irreversible electrochemical oxidation, which was controlled by diffusion process. The peak current was linear to the squareroot of the scan rate in the range of 20 ~ 250 mV / s, and the process was controlled by diffusion. The method can be applied in the determination of terbutaline sulfate content in bricanyl tablets, which is simple, fast and sensitive. |
