3/1/2021 · BMP assay was conducted in 120 mL-serum vials with the working volume of 80 mL and the inoculum (VSS) to substrate (VS) ratio of 3:1 []. Each vial was flushed with 99.99% of N 2 to remove the oxygen in the vial headspace before being closed and sealed with the rubber stopper and aluminum cap.
The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand.
The rate constant for the vapor-phase reaction of dipropyl ether with photochemically-produced hydroxyl radicals is 1.85X10-11 cu cm/molecule-sec at 25 °C (1). This rate constant corresponds to an atmospheric half-life of about 21 hours at an atmospheric concentration of
