Real-time, Affordable Nitrate Detection in Water
M.Sc. student of Hadas Maman
Nitrates are a nitrogen-based ion that frequently enters water sources through agricultural runoff. The growth that it causes in the water, termed eutrophication, can lead to toxic algae blooms, dead aquatic zones, and other health concerns. Cheap sensing technologies, with the capability of real-time measurement and data networking, have the potential to protect communities and water sources across the globe. Electrochemical techniques are a relatively cheap and stand-alone method for measuring ionic content, such as nitrates, in a solution. Given that ions have an electrical charge, we can measure the magnitude of current that flows through a solution and thereby determine the concentration of the analyte. In order to effectively determine nitrate concentration and not broader ionic content, it is essential to understand chemical reaction pathways. In this research, we worked with several different types of electrodes, trying to control the chemical reactions taking place and thus measure specifically nitrate concentration.
