| 摘 要： | 用直流伏安法（DCV）、微分脉冲伏安法（DPV）和循环伏安法（CV）在玻璃电极（GCE）上研究了依沙吖啶（EAD）在不同介质中的阳极伏安行为，发现在0．1mol/L氢氧化钠溶液中于0．38V（vs.Ag/AgCl)左右产生一个良好的阳极氧化峰，浓度在0．05－80mg/L之间与其峰电流呈线性关系，用本法不需要分离，可直接测定药物制剂和加标尿样，RSD为1．4％－2．7％(n=10)。尿样中EAD的回收率为89％－95％。探讨了EAD在GEC上的电极反应机理。

| Abstract: | The anodic voltammetric behavior of ethacridine (FAD) in the presence of various electrolytes was studied by using linear potential sweep voltammetry, differential-pulse voltammetry and cyclic voltammetry at a glassy carbon electrode. In the medium of 0. 1 mol/L NaOH solution, an oxidative peak of ethacridine was obtained. The peak potential is at about 0.40 V(vs. Ag/AgCl). The peak current is linearly increased with the concentration of ethacridine over the range of 0. 05- 80 mg/L. The method has been used for the direct detennination of ethacridine in injection. The relative standard deviation (n = 10) is 1. 4% - 2. 7%. The recovenes of ethacridine in urine samples are 89% - 95%. The mechanism of the electrode reaction was also discussed. |
