Fill two BOD bottles completely full of BOD dilution water, being very careful not to introduce air into either bottle. 2. Analyze one bottle for D.O. using the
This method covers the determination of chemical oxygen demand (COD) in Laboratory Fortified Sample Matrix (LFM) -- An aliquot of an environmental.
Note: See DRB 200 user manual for selecting pre-programmed temperature applications. 3. Remove the cap of a. COD Digestion Reagent. Vial for the appropriate.
Both organic and inorganic components of a sample are subject to oxidation, but in most cases the organic component predominates and is of the greater interest.
The BOD5 value has been used and reported for many applications, most commonly to indicate the effects of sewage and other organic wastes on dissolved oxygen in.

What You Should Know. There are few listed interferences with the COD methods. The most common one encountered is the chloride ion, although any halogen will
BOD (biochemical oxygen demand). BOD is the traditional, most widely used test to establish concentration of organic matter in wastewater samples (i.e.,
