摘　　要：通过一步合成法制备了氧化石墨烯载钯纳米复合材料(PdNPs@GO)。该材料兼具GO和PdNPs的特性,将其修饰玻碳电极,构建了一种高灵敏度、低检测限、宽线性范围的甲基对硫磷电化学传感器。实验结果表明,该材料不仅增加了电极的有效比表面积,还提高了电极的导电性和电催化性能。最低检测限为6.536μg/L,并在19.608~579.000μg/L的浓度范围内具有良好的线性相关性。Graphene oxide supported palladium nanoparticle composites(PdNPs@GO)were successfully prepared by a one-step synthesis method.This material combines the characteristics of GO and PdNPs.A highly sensitive,low detection limit,and wide linear range electrochemical sensor for methyl parathion was constructed by modifying this material on the surface of a glassy carbon electrode.The experimental results show that this material not only increases the effective specific surface area of the electrode,but also improves the conductivity and electrocatalytic performance of the electrode.The minimum detection limit of the sensor is 6.536 g/L,and it has good linear correlation in the concentration range of 19.608-579.000μg/L.
