This oxidation is catalyzed by silver sulfate. The catalyst is needed, Specifically to oxidize very low molecular excess weight fatty acids. The oxidation via the acidified dichromate can be represented by the next equation:
Make sure that the reagent blank vial is identical good deal number since the test vials. Be aware: At the very least a person reagent blank has to be run with Just about every list of samples with each new large amount range of COD test vials.
COD can be a key indicator of h2o good quality and is particularly utilized in a variety of purposes, such as the following:
Higher COD concentrations in wastewater point out the existence of natural and organic substances that will reduce the amount of dissolved oxygen.
Nền tảng cho thử nghiệm COD là gần như mọi hợp chất hữu cơ đều có thể bị oxy hóa đầy đủ để tạo ra dioxide cacbon bằng các chất oxy hóa mạnh trong các điều kiện axít.

Just after dilution, the resulting distinction between the Preliminary and last DO reading simply needs to be multiplied with the dilution issue to find out the final BOD outcome.
In summary, it truly is preferable to focus on the importance of TOC and the possibility of applying This system as being a complementary Software to check here verify the outcome attained by other approaches.
COD describes the level of oxygen necessary to chemically break down pollutants, whilst BOD signifies the quantity of oxygen required to stop working natural pollutants biologically with microorganisms.
Chemical Oxygen Demand (COD) can be a measure of the quantity of check here oxygen necessary to chemically oxidize organic and inorganic compounds present in water. It offers an estimation of the quantity of pollutants which can be oxidized by powerful chemical oxidants.
Now we have school and personnel in just about every county over the state that exist To help you. For information and facts or maybe the standing on programs, Get in touch with your neighborhood Extension office by e mail or mobile phone.
Significant COD stages can show a high volume of natural pollutants from the wastewater, which may be harmful into the natural environment and human overall health. Consequently, reducing the COD in wastewater in advance of it is actually discharged is a major goal of wastewater therapy procedures.
