TOC measures natural carbon but various organic molecules will crank out distinctive oxygen demand. Measuring TOC on your own won't essentially point out the amount oxygen will likely be eaten by the organics within the ecosystem. One example is, oxalic acid and ethanol generate identical TOC success. Nevertheless, because of various oxidation states, the oxygen demand of ethanol is six occasions bigger than oxalic acid, that means ethanol will likely have a bigger effect on the dissolved oxygen content material of a getting drinking water.
