In this field, the researchers of the MP4MNP group stand out for the study and creation of customized sensors dedicated to the in-situ detection of pollutants The sensors for detecting pollutants exploit the electrochemical principles of voltammetry, which measures the current as a function of the applied potential, to measure heavy metal ions, such as arsenic, in marine, groundwater and drinking water. This technique is extremely sensitive, detecting pollutant concentrations down to ppb (μg/L) levels, and selective, distinguishing between different oxidation states of electro-active species. For the monitoring of other heavy metals, such as Chromium (VI), in high concentrations of grams per liter (g/L), the sensors can also be configured according to colorimetric UV-Vis spectrophotometry methodologies and implemented with different systems for identification of basic chemical-physical parameters (temperature, pH, conductivity, ORP potential, etc.). Finally, thanks to the development of advanced sensor platforms, such as Autonomous Underwater Vehicles (AUV), which synergistically integrate the sensors described, it is possible to carry out a complete evaluation of water quality.
