Enhanced Effect of Enhancing Agents on the Oxidation Reaction Catalyzed by Mimetic Horseradish Peroxidase——Fe-TPPS4-4-AAP-Phenol-H2O2 System
Abstract:
The enhanced effect of U-cyclodextrin(U-CD) or surfactants on the oxidation reaction of H2O2 with 4-aminoantipyrine and phenol, using iron-(4-sulphophenyl) porphine (Fe-TPPS4) as catalyst has been studied. It is indicated that the initial rate and sensitivity of this color reaction are increased with the added amount of U-CD or sodium dodecylbenzene sulfate(SDBS). A sensitive method for the determination of H2O2 in the presence of U-CD has been developed. Trace amount of SDBS can be determined based on the linear relationship between the increment of the reaction rate and the concentration of the surfactant.
