Abstract

Pharmaceuticals and other micropollutants has been the focus of recent research due their occurrence in different environmental compartments worldwide. These compounds have limited degradation in the environment and continuous introduction through various wastewaters. Among these pollutants, antibiotics have attracted attention due to their biological activity and the possibility to cause the development of resistance genes in bacteria of the environment, reducing long-term effectiveness of these compounds. Additionally, several studies focus on forms of wastewater treatment for the removal of these xenobiotics, but few studies focus on the determination of these substances to be carried out a monitoring of pre-and post-treatment of effluents. Therefore, this project aims to develop electrochemical devices coupled with nanotechnology to the development of modern strategies of analysis. Nanotechnology has been an ally for the production of materials with improved performance, greater efficiency, durability, and this project aims to develop innovative nanostructured sensors for monitoring pyrimidines and sulfonamides in wastewater.
