Chemical Oxygen Demand Calculator
Posted by Dinesh onOnline chemical oxygen demand (COD) calculator to calculate or measure the amount of organic compounds in water. chemical oxygen demand test is commonly used test, which helps to indirectly estimate the amount of organic pollutants found in surface water. In general, COD is expressed in milligrams per liter (mg/L), which indicates the mass of oxygen consumed per liter of a solution.
COD (Chemical Oxygen Demand) Calculation
Formula:
COD = [(A - B × N × 8 × 1000)] / Volume of sample taken
Where,A = Volume of Ferrous Ammonium Sulphate for blank
B = Volume of Ferrous Ammonium Sulphate for sample
N = Normality of Ferrous Ammonium Sulphate
V = Volume of sample
