In this experiment, a highly effective electrochemical sensor based on a molecularly imprinted polymer has been developed for ultrasensitive detection of dimetridazole. The sensor was made by incorporating of dimetridazole as a template molecule during the electropolymerization of poly-arginine on a glassy carbon electrode. The modified electrode GCE/P-Arg@MIP was characterized by voltammetric and microscopic techniques. Differential pulse voltammetry method was used to detect target analyte under the optimum condition. The DPV response to dimetridazole was linear at 0.1 × 10 to 10 × 10 mol L (R = 0.996), with a method detection limit (S/N = 3) of 0.1 × 10 mol L. Moreover, the proposed sensor shows satisfactory recovery ranges for the determination dimetridazole in commercially available egg, milk and honey samples.
在这项实验中,我们开发了一种基于分子印迹聚合物的高效电化学传感器,用于超灵敏检测二甲硝唑。该传感器是通过在玻碳电极上电聚合聚精氨酸的过程中加入二甲硝唑作为模板分子制成的。修饰电极 GCE/P-Arg@MIP 采用伏安法和显微镜技术进行了表征。在最佳条件下,采用差分脉冲伏安法检测目标分析物。DPV 对二甲硝唑的响应在 0.1×10 至 10×10 mol L(R=0.996)范围内呈线性,方法检测限(S/N=3)为 0.1×10 mol L。此外,该传感器在市售鸡蛋、牛奶和蜂蜜样品中测定二甲硝唑时表现出令人满意的回收率范围。
