Abstract

A new promising mimetic enzyme, a [2Fe-2S] cluster-porphyrin hybrid complex ([2Fe-2S]2TPPS), has been synthesized and applied to the determination of hydrogen peroxide. Under the optimum condition, the calibration graph has a linear range of 8.0 x 10(-8) - 1.0 x 10(6) mol/l H2O2 with a detection limit (3sigma, N = 9) of 5.3 x 10(-9) mol/l.
