Abstract	Incompatibility between Fenton’s Reagents and a potassium dichromate COD test provides interference that prevent accurate measurements of the concentration of organics from oxidized samples. Several treatment options were tested to remove this interference. Oxidation of reagents was eliminated as a potential method for removal of interference due to sample contamination. Potassium iodide was used to remove the interference of hydrogen peroxide from samples through catalysis of its decomposition. pH adjustment was capable of eliminating the interference of ferrous iron through precipitation at the expense of removing the target analyte from solution. Key Words: Fenton’s Process, hydrogen peroxide, ferrous iron, COD assay, assay interference
