Chemical Oxygen Demand (COD) Calculator Online. The Chemical Oxygen Demand or COD, is a measurement of the amount of material that can be oxidized (combined with oxygen) in the presence of a strong chemical oxidizing agent. More specifically, the test is a process of decomposing pollutants in water after two hours of boiling the water in a solution of potassium dichromate. COD Calculator calculates Chemical Oxygen Demand in a Water.
Chemical Oxygen Demand (COD) = (A-B)xMx8000 / Volume of Sample mL
- A : mL of titrant used for sample
- B : mL of titrant used for blank
- M : Normality of ferrous ammonium sulfate
