molecules giving an average absorption coefficient.
That means that the instrument must be calibrated
according to a COD laboratory measurement before
using.
Also, the ratio of the different molecules must remains
approximately constant to assume a good correlation
with laboratory COD.
The UV absorption can be considered as an alternative
method for COD [Chemical Oxygen Demand] when
fast, reliable and inexpensive measurements with very
low maintenance are required.
