CO2 dissolved in wastewater will form carbonic acid (a weak acid), which in turn reacts with caustic wastes to neutralize the excess alkalinity as follows: 27. CO2 + H2O → H2CO3, flue gas wastewater carbonic acid H2CO3 + 2NaOH → Na2CO3 + 2H2O, carbonic acid caustic soda in wastewater soda ashash H2CO3 + Na2CO3 → 2NaHCO3 + H2O.

The reaction works best with a catalyst such as vanadium pentoxide or iron. The nitric oxide is used to regenerate nitric acid. Another method for the production of oxalic acid started from cellulose. To this end, sawdust was subjected to an oxidizing alkali melt. This procedure gave only low yields also, the amount of wastewater was very high.
