Oxygen consumption chemical basis

The effects of 8 transition metals were studied in a nitrifying system to investigate the relationship between the ionic characteristics of metals and their toxicity to nitrifiers. The cumulative oxygen consumption and the cumulative carbon dioxide production were monitored throughout each respirometric batch run to determine the toxicity of metals to nitrifiers. Several QCAR models were developed on the basis of these different toxicity endpoints using quantum chemical descriptors. [Pg.170]

The results are quoted as oxidizability (potassium permanganate consumption) in mg/1 KMnO/ and additionally in mg/1 (oxygen equivalent) in a similar manner to the chemical oxygen demand. On the basis of the stoichiometric relationships... [Pg.483]
