Digestion is completed by refluxing (150 °C). The excess of dichromate is usually determined by titration or spectrophotometry, and using mercury salts to eradicate the interference because of chlorine is required. Dichromate is considered as the ideal oxidizing agent and the ready solution is secure for some time, the main dilemma that shows may be the technology of remarkably poisonous squander [12, fifty nine].

 Alternatively, the absorbance of hexavalent chromium at 420 nm may be used to ascertain the quantity of excess chromium at the end of digestion to ascertain COD values.
