Abstract

This research project internship abroad (BEPE) is related to the PhD projectFAPESP 2016/09634-0, which involves the detection of the herbicides atrazine (ATZ),prometryn (PRM), and ametryn (AMT) by surface-enhanced Raman scattering (SERS),for limits of water potability below than those determined by regulatory agencies.Thedetection of these herbicides are complementary to the proposal of the PhD project inprogress, once the silver nanoparticles (AgNPs) will be obtained via reduction withhumic substances (HS) in the context of green chemistry. In this way, the intention is toreduce the use of solvents, reagents, or toxic products generated, minimizing thedamage to human health and environment. For that, we will have the collaboration ofDr. Santiago Sanchez Cortés from CSIC/Madrid, Spain, a specialist in the synthesis ofmetallic nanoparticles for SERS application as an analytical tool in the detection ofdiverse analytes, and with whom our Research Group already has established animportant collaboration.
