▎ 摘　　要

NOVELTY - The electrode has an electrode substrate which is coated on the surface of the ion-selective polymer film. The electrode substrate is doped with modified graphene or graphene film by electrodeposition. The electrode substrate is made of carbon paste, graphite, paraffin oil, ion liquid and triphenylamine. Titanium dioxide nanowire is provided on the surface of graphene film. Graphene oxide film is provided on the surface of glassy carbon electrode. USE - Ion selective electrode used for detecting solution ion concentration. ADVANTAGE - The preparation of the ion selective electrode is simplified. The cost can be reduced. The electrode has stable potential. The sensitivity and selectivity can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for ion selective electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating the relationship between the electrochemical impedance response of electrode substrate and glassy carbon electrode.(Drawing includes non-English language text)
