3-Nitrophenol

3-Nitrophenol is an organic compound that is used in wastewater treatment, specifically to remove nitrogenous compounds from the water. It reacts with a hydroxyl group and a nitro group to form a molecule with three nitro groups. The presence of this molecule in wastewater can lead to population growth, which may be reduced by thermal expansion. 3-Nitrophenol is also used as an electrode for gravimetric analysis of metals and as a reagent for the detection of sodium ions. This compound has been shown to have a ph optimum of 7.5, but will react with hydrogen bonds at any ph value.
