A COD test typically involves digestion of a water sample in a sealed vial with potassium dichromate and sulfuric acid at 150oC for 2 hours. Why test for COD?
BOD (biochemical oxygen demand). BOD is the traditional, most widely used test to establish concentration of organic matter in wastewater samples (i.e.,
