Classified as a hazardous substance under EPA regulations, ammonia is a colorless gas that carries a distinctly sharp odor. A compound of nitrogen and hydrogen molecules, it dissolves easily in water, entering environmental waters through decomposition of nitrogen-containing compounds.
Spectroscopic techniques for ammonia determination may require an additional distillation step, while ion chromatography (IC) can determine ammonium and its inorganic cations in a single run.
In the U.S., the ammonium cation (NH4) is measured for wastewater discharge compliance. In the EU and Japan, ammonia is monitored in both wastewater and drinking water.
