RP4: Aqu. ammonia, aqu. urea and nitrate monitoring sensors (ESR4, UoG)

Ammonium, nitrate and urea are often observed in field water samples due to many chemical fertilizers. The measurement of these analytes provides information on metabolic processes of water bodies. The concentration of NO3− and NH4+is the major factor which control the level of inorganic nitrogen species. Fertilizers, high temperature combustion sources and sewage, lead to increased concentration of these analytes and therefore monitoring these parameters in water is important for better aquatic life. To monitor, these parameters over a low to high concentration range, highly sensitive nanostructured material based sensors will be developed in this project.
