Diffusion coefficients for metol and p-benzenediol were 2.1×10 cm^2/s and 2.7×10^6 cm^2/s, respectively. The electrocatalysis mechanism has been studied. ATR-FTIR was used for the characterization of the ME/Au SAMs. The oxidation currents were linear in the range of 1.0×10^(-7)~1.0×10^(-4)mol/L for metol and 6.0×10^(-6)~6.0×10^(-4)mol/L for p-benzenediol, with the correlation coefficients of 0. 9992 and 0.9996 by differential pulse voltammetry, and detection limit 2.0×10^(-8)mol/L and 1.2×10^(-6) mol/L for metol and p-benzenediol, respectively.
