2018/11/1 · A COD test indirectly measures the concentration of organic compounds in a sample of water by measuring the amount of oxygen required for oxidation of all the organic compounds present. The common technique uses COD vials for measurement and results are typically achieved within 2

ASTM D 1252-00, Chemical Oxygen Demand (Dichromate Oxygen Demand) of Water, Test Method B. CHEMetrics offers two dichromate reactor digestion methods for fast, easy, safe determinations of low-, mid-, and high-range COD levels in wastewater: the USEPA-accepted Method*, and a mercury-free method. The products using the USEPA-accepted method

For samples with a concentration of 0 to 150 mg/L, use the low range COD vials. For higher concentrations the high range COD vials (0-1500 mg/L) should be used.

2017/6/1 · The oxidation of KHP was reproducible in a COD range of 20–500 mg/L with a mean recovery rate of 88.7% in comparison to the standard COD method (DIN

2020/9/2 · The COD levels vary, but are all within the range for that reagent set and cover the minimum and maximum to ensure the full expected range for samples are covered by the calibration. If the chloride concentrations are not consistent from sample to sample, then there unfortunately is not a …

Government regulation Many governments impose strict regulations regarding the maximum chemical oxygen demand allowed in waste water before they can be returned to the environment. For example, in Switzerland, a maximum oxygen demand between 200 and 1000 mg/L must be reached before waste water or industrial water can be returned to the environment .
