利用扫描电镜(SEM)和交流阻抗谱法(EIS)对以滴涂法制备的羧基化单壁碳纳米管(SWCNTs-COOH)修饰玻碳电极进行纳米膜特性表征,并采用循环伏安法(CV)研究了氯霉素(CAP)在其上的电化学行为.结果表明,SWCNTs-COOH修饰的玻碳电极对CAP的还原有良好的电催化作用,根据实验结果推测为双质子双电子还原过程,CAP在修饰电极上的扩散系数及反应速率常数分别为8.76×10-4cm2/s及1.64×10-3s-1.在实验优化选定的测试条件下,还原峰(-0.602 V)电流与CAP的浓度在1.55%By using the scanning electron microscopy(SEM) and the electrochemical impedance spectroscopy(EIS) construct surface features of the single-walled carbon nanotubes with carboxyl(SWCNTs-COOH) on the N,N-dimethylformide solution and dropped on the surface o
