Hg (II) ion electrochemical detection electrode based on amorphous palladium nano composite material and preparation method of Hg (II) ion electrochemical detection electrode

The invention provides an amorphous palladium nano-composite electrode for detecting heavy metal Hg (II) ions and a preparation method of the amorphous palladium nano-composite electrode. In particular to a preparation method and application of a composite electrode formed by modifying an amorphous palladium-based reduced graphene oxide (Pd-P-RGO) nano composite material on a glassy carbon electrode (GCE). The electrochemical sensing nano material applied to mercury ion monitoring is successfully prepared through a chemical reduction method, specifically, hexadecylpyridinium chloride-hydrate (HDPC) is used as a structure-directing agent, an amorphous palladium-based reduced graphene oxide (Pd-P-RGO) nano composite material reduced by sodium hypophosphite is used, and the nano composite material is used as a modifier of a glassy carbon electrode (GCE). And determining the Hg (II) in the actual water sample by differential pulse anodic stripping voltammetry (DPASV). The composite electrode has good electron tra
