A preparation method of nano-silver/pyridine-functionalized graphene modified electrode, characterized in that: comprising pyridine-functionalized graphene (Py-GO) synthesis, Ag nanoparticles/pyridine-functionalized graphene (AgNPs/Py-RGO) synthesis and the preparation of AgNPs/Py-RGO/GCE, the synthesis of AgNPs/Py-RGO is to add silver nitrate and ethylenediaminetetraacetic acid to the Py-GO dispersion to form a mixed solution, water bath to boiling, and then slowly add hydroboration Sodium, heated continuously, then centrifuged and dried. The AgNPs/Py-RGO/GCE prepared by the invention has a high Ag loading, and the Ag content accounts for 39.62wt%; the Ag nanoparticles have a uniform particle size, are evenly distributed on the graphene surface, and do not agglomerate; AgNPs/Py-RGO/ GCE has excellent detection sensitivity for HQ and CC, with detection limits of 0.062 μM and 0.097 μM, respectively; excellent selectivity and strong anti-interference ability. |
