ABSTRACT:
A method of the present invention is provided for removing low molecular weight contaminants from a contaminant-containing material. This contaminant-containing material can include alcohol compounds, aldehyde compounds and peroxide compounds. The method comprises providing an alcohol oxidase enzyme-based catalyst system including coimmobilized transition metals comprising platinum and copper for catalytically oxidizing the contaminant-containing material. Then, the contaminant-containing material is catalytically oxidized in the presence of the alcohol oxidase enzyme-based catalyst system to form organic acid compounds. The organic acid compounds can then be removed.
