Ethylenediaminetetraacetic acid (EDTA) was found to incompletely oxidize in chemical oxygen demand (COD) analysis, leading to incorrect COD values for water samples containing relatively large amounts of EDTA. The degree of oxidation depended on the oxidant used, its concentration, and the length of

Chemical oxygen demand is generally reported in terms of oxygen, with 1 mole Cr2072~ being equivalent to 1.5 mole 02. As shown in eq 2, this equates to 8.5 moles 02 per mole EDTA4- or 0.944 g COD/g EDTA4". In this report
