Two Schiff base complexes containing Cu(Ⅱ) were used as mimetic peroxidase in the catalytic oxidation of phenol by H2O2. The characteristic spectra of the Schiff base complexes in buffered solution and H2O2-buffered solution were analyzed. The mechanism and the kinetic mathematic model of phenol oxidation catalyzed by the Schiff base complex containing Cu(Ⅱ) were studied. The effect of [H2O2]/[complex] molar ratio, pH, temperature and the micelles on the reactive rate was discussed. The results showed that Schiff base complexes containing Cu(Ⅱ) exhibited the character of the peroxidase under different conditions in the catalytic reaction.

Key words: Schiff base complex containing Cu(Ⅱ), mimetic peroxidase, kinetics
