制备了Pd-Au复合纳米粒子修饰玻碳电极(Pd-Au/GCE),研究了芦丁在Pd-Au/GCE修饰电极上的电化学行为,该修饰电极对芦丁的电化学氧化有明显的催化作用。用循环伏安法(CV)对芦丁进行了测定,其氧化峰电流与芦丁的浓度在2.5×10-6~7.5×10-5mol/L范围内呈良好的线性关系,线性相关系数为0.9971,检出限(S/N=3)为1.0×10-7。方法可用于市售芦丁片中芦丁含量的测定,标准加入法的回收率在87.7%~103.1%之间。 The electrochemical behavior of rutin on Pd-Au / GCE modified electrode was investigated by Pd-Au composite nanoparticle modified glassy carbon electrode (Pd-Au / GCE). The electrochemical oxidation of rutin The catalytic role. The rutin was determined by cyclic voltammetry (CV). The peak current of the rutin was linear with the concentration of rutin in the range of 2.5 × 10-6 ~ 7.5 × 10-5mol / L. The linear correlation coefficient was 0.9971, and the detection limit (S / N = 3) was 1.0 × 10-7. The method was applied to the determination of rutin in commercial rutin tablets. The recoveries of standard addition method ranged from 87.7% to 103.1%.
