An Eastman-AQ/Ni(Ⅱ) chemically modified electrode (CME) produced by "double coating steps" deposition of Eastman-AQ/Ni(Ⅱ) film and Ni(Ⅱ)-coating crystalline species onto glassy carbon instead of metallic nickel electrode exhibited stable electrocatalytic oxidation of numerous α-hydrogen compounds including carbohydrates,amines and amino acids.Determination of glucose in FIA on the CME,the linear response concentration range was bstween 1.0×10^-5 and 5.0×10^-2 mol/L and the detection limit was 5.0×10^-6mol/L.The stability of the CME was adequate for routine quantitative application.
