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). A COD test can be used to easily quantify the amount of organics in water. The most common application

The better results of the kits could also be explai ned with a better seal of the screw-cap on the tube because of the “single-use” of the kit vials. Table 5 Results obtained using the closed reflux method at L1. 10 mL headspace in the vials.

Jul 13, 2020 · Biological oxygen demand (BOD) is an empirical method carried out using predetermined laboratory procedures in assessing the relative oxygen requirements of wastewater, polluted water and effluents. The values of BOD signify the quantity of biodegradable organic material (carbonaceous demand) and the oxygen required to oxidize inorganic

ABSTRACT: To accurately measure the oxygen demand of a wastewater sample in a headspace biochemical oxygen demand (HBOD) or other respirometric test, the rate of oxygen transfer to the aqueous phase must be greater than the oxygen exertion rate by the sample. Oxygen mass-transfer coefficients (Kawa) measured for 28-, 55-, and
