Abstract

The environmental impact directly caused by various types of emerging contaminants (EC) has led to a growing interest in the development of alternatives for their removal and/or oxidation to simpler substances. These environmental remediation alternatives are directly related to the way in which contaminants interact with the matrices used for their removal or with the radical mechanisms responsible for their oxidation. Some examples of EC are microplastics, which can currently be found in different bodies of water and in the atmosphere, hormones and mediciness that cause problems to human health. Among the matrices currently used for EC removal are graphitic carbon nitride, nanotubes, reduced graphene oxide and biopolymers that have excellent properties for the interaction/adsorption of these substances. In this context, knowledge of the electronic structure of the molecules involved allows us to understand how the interaction processes occur, determining the energies, thermodynamic, structural and electronic properties of the systems. In conjunction with theoretical results, experimental analyzes can help and contribute significantly to current challenges. Therefore, this project will carry out an integrated study of these phenomena using molecular quantum chemistry methods, providing different parameters and combining them with experimental results. Furthermore, it will contribute to the beginning of the formation of a theoretical group integrated with different experimental groups in Brazil. (AU)
