A COD test normally will involve digestion of a h2o sample in a very sealed vial with potassium dichromate and sulfuric acid at 150oC for 2 hrs.

Are any test methods accessible for desalination plants or other laboratories needing to test seawater, brackish, or polluted waters with large chloride degrees?

Sir, if right after managing the sample, the sample turns darkish crimson and after the 2hrs heating, the colour continues to be the same, read more how do we determine the COD?
