Cobalt based solid state phosphate sensor with submicromolar detection range

Phosphate monitoring is critical in assessing the nutrient pollution in water bodies like lakes and rivers, and in their management. Increase in phosphate concentration can result in algal bloom in the water bodies. Most of the commercial system uses colorimetric methods for phosphate measurements. However, these methods require reagents that may not be suitable for long term field use. Electrochemical methods such as potentiometry offer a good …
