Higher COD concentrations in wastewater indicate the presence of organic and natural substances that could reduce the amount of dissolved oxygen.
ISO-compliant reagents: Conform to ISO 15705:2002 approaches with regard for their composition. These compositions of these COD vials are much like that of EPA criteria, so In addition they include mercury.
Digestion is completed by refluxing (one hundred fifty °C). The surplus of dichromate could be based on titration or spectrophotometry, and applying mercury salts to do away with the interference attributable to chlorine is needed. Dichromate is regarded as the most effective oxidizing agent plus the well prepared Alternative is steady for years, the main difficulty that exhibits is definitely the generation website of hugely poisonous waste [12, 59].
