What is Chemical Oxygen Demand (COD)? Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters.

METHOD #: 410.1. Chemical Oxygen Demand (Titrimetric, Mid-Level) COD Chemical Oxygen Demand. 1.0 Scope and Application. 1.1 The Chemical Oxygen Demand (COD) method determines the quantity of oxygen required to oxidize the organic matter in a waste sample, under specific conditions of oxidizing agent, temperature, and time.
2019/11/11 · Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and, Total Organic Carbon (TOC) compromise the three main methods of testing water samples. BOD and COD methods differ from TOC because they measure the amount of oxygen that is depleted by organic species in water. Moreover, TOC is a measure of all carbon (both organic and inorganic
2021/04/13 · When measuring Total Hardness, you can use the drop-count test method or CHEMetrics Titrets ampoules. The CHEMetrics test is superior. Titrant and buffer are pre-measured and indicator is pre-dosed, so there's no need to add individual reagents, and you don’t have to count drops – but you *can* count on CHEMetrics for simplicity in water analysis.
