rrelate two or more of these values for a given sample. BOD is a measure of oxygen consumed by microorganisms under specific conditions; TOC is a measure of organic carbon in a sample; …

Calculate the chemical oxygen demand by following formula: COD = 8*1000*DF*M*(VB - VS) / Volume of sample (in ml) Where, DF – Dilution Factor (if applicable)

1.2 This method covers the determination of chemical oxygen demand (COD) in ground and surface waters, domestic and industrial wastes. 2.3 Sample, blanks, and standards in sealed …

Chemical oxygen demand is a vital test for assessing the quality of effluents and waste waters prior to discharge. The Chemical Oxygen Demand (COD) test predicts the oxygen requirement …

Biological oxygen demand (BOD), chemical oxygen demand (COD), and total organic carbon (TOC) are parameters used to measure the organic “strength” of the wastewater.

The mg/L COD results are defined as the mg of O2 consumed per liter of sample under the conditions of this procedure. In this procedure, the sample is heated for two hours with a …

Switching to "M" or "2M" COD Tubetests will increase the suppression of this interference and/or the sample can be diluted prior to the test to reduce the chloride concentration
