Metal nanoparticle carbon nanocomposites to produce electrochemical devices for environmental water monitoring

Venue: Sala d'Actes Carles Miravitlles, ICMAB-CSIC.


With the development of industry and agriculture, large amounts of wastewater are produced and discharged. The increasing awareness that water is a finite, vulnerable resource calls for increased monitoring and treatment of the produced pollutants. The main objective of this thesis was the development of novel sustainable electrochemical sensors for the sensitive analysis of water pollutants.

In particular, we focused on the measurement of Chemical Oxygen Demand (COD), and the quantitative detection of organohalides and heavy metals. To this aim, metal nanoparticle-modified porous carbon nanocomposites were synthesized and further processed to manufacture miniaturized thick-film and thin-film electrochemical devices by screen printing and microfabrication techniques. A full assessment of the analytical performance of the different devices was carried out.
