Abstract

This project comprises the development of carbon nanomaterials for the removal of ubiquitous contaminants in produced water (PW), which is the largest waste stream from oil and natural gas production, therefore, an important source of contamination of water resources. Initially, advanced materials, which consist of carbon nanotubes and composites based on graphene oxide and biopolymer, will be produced via conventional and green syntheses and functionalized. These innovative nanomaterials will be characterized by a series of analyses and techniques and, later, evaluate the effect of removal processes on their structure. The potential of these materials in adsorption processes will be evaluated for the removal of common pollutants in PW, such as naphthenic acids, polycyclic hydrocarbons, and phenol. The effects of fundamental parameters such as adsorbent dosage, pH of the solution, and concentration of contaminants will be studied. Furthermore, analyses of kinetics, mass transfer, equilibrium, thermodynamics, desorption in a bath system, reuse capacity; molecular modelling of adsorbate, and application of mathematical and phenomenological models to elucidate the nature of the process will be performed. The project also aims to evaluate the degradation capacity of composites in advanced oxidative processes, through kinetic and phytotoxicity studies, as well as to study the synergy in combined adsorption and oxidation processes. In addition, this project aims to train highly qualified human resources. (AU)
