As dichromate ion oxidizes natural make any difference within the sample, it can be reduced to chromic ion, which happens to be reflected by a alter in color from orange or yellow to environmentally friendly. The sample is then read in the photometer or spectrophotometer to evaluate the alter in coloration.

One vial is marked as being a “blank,” and a few or 4 vials are marked with acknowledged standard concentrations. Two vials are then marked to the wastewater sample to create a duplicate run. Take note: If numerous wastewater samples are increasingly being operate, at the least 10% of samples are duplicated.

The way forward for COD measurement lies in the event of safer, far more accurate, and a lot more effective techniques. As our idea of the nature and habits of natural compounds in drinking water improves, so far too will our ability to measure and Regulate their effect on the environment.
