Abstract: The enhanced effect of β-cyclodextrin(β-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 β-CD or sodium dodecylbenzene sulfate(SDBS). A sensitive method for the determination of H2O2 in the presence of β-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.

Key words: β-cyclodextrin, surfactant, mimetic enzyme, H2O2 determination, enhanced spectrophotometry
