Abstract

In this research project, the modification of reduced graphene oxide (rGO) with gold nanoparticles (AuNPs) for the determination of the sulfamethazine antibiotic in swine effluent will be evaluated. The presence of sulfamethazine in environmental compartments is often related to contamination by wastewater of the intensive rearing of animals, mainly swine. Methodologies of treatment these effluents and appropriate analytical strategies, with the goal of determining this antibiotic at low concentration levels in these complex samples are extremely important. Thus, this project aims at the development of an electrochemical device that is promising for simple, rapid, direct and sensitive for analysis of sulfamethazine in swine effluent.
