| 摘 要： | 介绍了一种制备碳纤电极的新方法，并研究了盐酸氨溴索在铋膜修饰的碳纤电极上的电化学响应。实验表明，在0．5mol／LH2SO4底液中，用示差脉冲伏安法进行扫描时，发现盐酸氨溴索在1．10V（vs．SCE）处出现一阳极峰，且峰电流与盐酸氨溴索的浓度在6．26×10^-8～4．64×10^-5mol／L范围内呈良好的线性关系，该方法的检出下限为4．0×10^-8mol／L。用标准加入法测得回收率范围为92．8％-102％，RSD为2．9％。将此电极用于实际样品的测定，取得较好的结果。

| Abstract: | A new method of preparation of carbon fiber electrode（CFE）, as described in the present paper. Such CFES have low noise level. The ambroxol hydrochloride was determined with a carbon fiber electrode modified with bismuth film by differential pulse voltammetry（DPV） at 1.10V （vs. SCE） in 0.5mol/LH2SO4. The peak currents at 1. 10V are proportional to ambroxol concentration in the rage of 6. 26×10^-8 -4. 64×10^-5 mol/L with the detection limit of 4.0×10^-8 mol/L. The response mechanism of electrode was discussed. The anodic oxide of ambroxol at 1.10V is irreversible. |
