Colorimetric assay of H2O2 using Fe3O4 nanoparticles as nanocatalyst
Fe3O4 nanoparticles were prepared,and catalyzed the reaction of H2O2-methyl orange.In pH 1.42 HCI-NaAc buffer solution,methyl orange has two absorption peaks at 331nm and 506 nm.When Fe3O4 nanoparticles was added,it can catalyzed H2O2 oxidizing methyl orange to result in the absorption value decreascd at 506 nm.The decreased absorption value is linear with the concentration of H2O2 in the range of 3.5-33 μmol/L.Based on this,a new colorirnetric assay has been proposed for the determination of H2O2 in the water sample,with satisfactory results.
