There are several methods for measuring COD, Just about every with its benefits and drawbacks. The commonest approaches consist of the dichromate strategy, the permanganate method, as well as the closed reflux approach.
Water High quality Assessment: COD measurement is a important tool for examining the overall pollution level and natural and organic material of h2o. Substantial COD values suggest the existence of substantial amounts of organic and natural pollutants, for example wastewater, industrial effluents, or natural and organic chemicals. Checking COD will help in evaluating the water high quality and determining resources of air pollution.
This technique is similar on the dichromate strategy but employs potassium permanganate as opposed to potassium dichromate. It's got the benefit of with the ability to differentiate among biologically offered and inert organic make a difference, however it is fewer accurate and a lot more time-consuming than the dichromate technique.

If your wastewater sample is tested at entire strength, then two ml is additional into the corresponding vial. If dilution is required, then serial dilutions are executed and 2 ml of your diluted sample are included for the corresponding vial.
Later on, you can determine simply how much dichromate went towards oxidizing organic and natural content depending on just how much we to begin with additional and the amount of was left over.
