Received Date:  2019-10-09

Fund Project:  This work was supported by the National Natural Science Foundation of China (No. 21365004), the Key Research and Development Plan of Guangxi (No. AB18126048), the Major Science and Technology Projects in Guangxi (No.AA18118013-10), the Project of Basic Ability Improvement of Young and Middle-aged Teachers of Universities in Guangxi (No. 2017KY0164), and the Youth Fund Poject of Guangxi University for Nationalities (No. 2018MDQN004).

以甲基对硫磷为模板分子,甲基丙烯酸为功能单体,马来松香丙烯酸乙二醇酯为交联剂,在石墨烯修饰的玻碳电极表面合成分子印迹聚合物膜,制备分子印迹电化学传感器,用于检测有机磷农药甲基对硫磷。采用循环伏安法、微分脉冲伏安法、电化学交流阻抗法研究传感器的电化学特性及分析特性。结果表明,在最佳检测条件下,传感器的峰电流与甲基对硫磷浓度在1.0×10-7-8.0×10-5 mol/L范围内呈线性关系,线性方程为Ip(μA)=-0.65199-0.02387C(μmol/L),相关系数R2为0.9922,检出限为5.0×10-8 mol/L(S/N=3)。构建了传感器的动力学吸附模型,测得印迹传感器的结合速率常数k=20.2758s。将此传感器用于番茄样品中甲基对硫磷的检测,加标回收率为95.0%~100.3%。
