【Abstract】 Self-assembled monolayer of Schiff base, which was formed on Au substrate,was investigated with electrochemical impedance spectroscopy(EIS) method.The effect of pH value of the system on the self-assembled monolayer and its complexation with Cu 2+ were all considered.The results suggest that the capacitance of the Schiff base membrane varys with the pH value of the solution regularly when the system is acidic.The EIS technique also confirm the reaction of Schiff base with Cu 2+,moreover,the different concentration of Cu 2+ will result in various complexation time.更多还原
