A COD standard solution (100 mg/L) in water obtained from VWR was used to test the accuracy and precision of this method. An oven (or thermoreactor) was preheated to 148 oC. After removing the screw cap from a COD vial, 2.0 ml of the 100 mg/L COD
2009/4/1 · Chemical oxygen demand (COD) is a measure of the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as ammonia and nitrite. COD measurements are commonly made on samples of waste watersor of natural waters contaminated by domestic or industrial wastes.

The 910 colorimeter is a rugged, waterproof, single parameter instrument for the measurement of COD (chemical oxygen demand). The EPA-approved COD test is useful for performing rapid, frequent monitoring of treatment plant efficiency, and results allow quick response to changing conditions in the waste stream while the traditional BOD5 test takes 5-days to determine results.
2009/7/13 · Chemical oxygen demand is related to biochemical oxygen demand (BOD), another standard test for assaying the oxygen-demanding strength of waste waters. However, biochemicaloxygen demand only measures the amount of oxygen consumed by microbial oxidation and is most relevant to waters rich in organic matter.
