Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).

2021/7/29 · The chemical oxygen demand (COD) is a measure of water and wastewater quality. The COD test is often used to monitor water treatment plant efficiency. This
2019/5/21 · Below is a comparison of the COD methods available: Option 1: Method 8000 with Hg-COD vials and ezCOD recycling service. United States Environmental Protection Agency (USEPA) approved for wastewater for reporting COD when using Low Range (LR) or High Range (HR) vials. An accurate and reliable method for determining COD with four different
2010/10/14 · Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown. One vial is marked as a “blank,” and three or four vials are marked with known standard levels.
After the treatment I did measure the COD using High range and low range vials for same sample but both vials showed different result for same sample , high range vials were showing 2324 mg/l
