Analytical electrochemistry for environment:electrochemical microsensors for the in situ monitoring of pollutants

摘要

This paper presents electrochemical microsensors allowing in situ monitoring of pollutants in water:heavy metals,ammonium,total organic carbon and organophosphorus pesticides.These microsensors are fabricated through microelectronics batch technologies.Their selectivity is obtained through the formulation of sensitive membrane including synthetic or biological molecules(enzymes).These microsensors allowing in situ measurements give an image in real time of the nature of the pollutants(biodisponibility of some heavy metals,toxicity of the aquatic medium).
