Polyacrylonitrile (PAN) and (CH₃COO)₂Zn were used as raw materials, and carbon nanofibers (CNFs) with high specific surface area were successfully prepared by an electrospinning method. A new method of electrochemiluminescence detection of azithromycin was established by modifying the glassy carbon electrode (GCE). Under the optimal conditions, the electrochemical behavior and electrochemiluminescence behavior of the Ru(bpy)₃²⁺-AZM system on the modified electrode were investigated. Owing to the large specific area, more active sites, and promotion of electron transfer, the sensor exhibits high electrocatalytic activity, high sensitivity, a good linear relationship ranging from to  mol/L, and a low detection limit ( mol/L). In addition, the good recoveries indicate that the sensor was a promising device for the detection of azithromycin in real samples.

高比表面积电纺纳米纤维制备修饰电极用于阿奇霉素电化学发光检测

以聚丙烯腈（PAN）和（CH ₃ COO）₂ Zn为原料，通过静电纺丝法成功制备了具有高比表面积的碳纳米纤维（CNFs）。通过对玻碳电极(GCE)的修饰，建立了阿奇霉素电化学发光检测的新方法。在最佳条件下，研究了Ru(bpy) ₃ ²⁺ -AZM体系在修饰电极上的电化学行为和电化学发光行为。由于比表面积大，活性位点多，促进电子转移，该传感器表现出高电催化活性，高灵敏度，良好的线性关系，范围从 至  mol/L，检测限低（ 摩尔/升）。此外，良好的回收率表明该传感器是检测实际样品中阿奇霉素的一种很有前途的装置。
