Any other information on results incl. tables
Deviation:
According to the Guideline the test temperature should not vary by more than ±1°C, The test temperature varied within ±1.3°C in this experiment
The test substance was not soluble in water, and was thus mixed with water to form an emulsion in order to measure COD.
The test substance was 100 % degraded, which is not possible as some carbon from the test material was incorporated into new cells. This high percentage can be cause by uncertainties in the measurements or the use of COD instead of ThOD.
