Abstract
In this paper, the use of a screen printed electrode modified by feather like La3+/ZnO nano-flowers for the determination of sertraline was described. These nano-flowers showed satisfactory catalytic activity for determination of sertraline by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. At the optimum pH of 7.0, the oxidation of sertraline occured at a potential about 280 mV less positive than that of an unmodified screen printed electrode. Based on DPV, the oxidation of sertraline exhibited a dynamic range between 0.5 and 150.0 µM and a detection limit (3σ) of 0.15 ± 0.01 µM. The modified electrode had a good performance for sertraline detection in real samples by the standard addition method.

羽毛状La 3+ / ZnO纳米花修饰的丝网印刷电极上舍曲林的电化学测定及其在药物和生物样品中的测定
摘要
在本文中,描述了用羽毛修饰的丝网印刷电极(如La 3+ / ZnO纳米花)测定舍曲林的用途。这些纳米花显示出令人满意的催化活性,用于通过循环伏安法(CV)和微分脉冲伏安法(DPV)方法测定舍曲林。在最佳pH值为7.0时,舍曲林的氧化反应发生的电位比未修饰的丝网印刷电极低约280 mV。基于DPV,舍曲林的氧化表现出0.5至150.0 µM的动态范围,检测限(3σ)为0.15±0.01 µM。通过标准添加方法,修饰的电极在实际样品中具有良好的舍曲林检测性能。
