摘要: Abstract Titanium dioxide (TiO2) and Fe3O4 magnetite particles were coated on spherical Kissirises; glucose oxidase (GOx) enzyme was immobilized Kissiris/Fe3O4/TiO2 by physical adsorption. Performance of the prepared biocatalyst in decolorization Malachite Green dye investigated. Ninety-nine percent obtained after 120 min using 2 g heterogeneous bio-Fenton catalyst at initial concentration 20 mg/L, 20 mM, pH 5.5 temperature 40 °C. In this process, contrast to conventional Fenton's reaction, external hydrogen peroxide ferrous ion sources not used.
