- Use of sewage treatment sludge in the synthesis of active carbon modified with nanostructured oxides (Ce, Nb, Ta, and Pd ) and its application in the electrochemical generation of hydrogen peroxide, BP.PD
Abstract
Stabilized sludge is the final waste of a production chain or from processes and is mostly thrown into landfills, without any type of viable reuse, and this project is therefore important for the environmental area, which can enable reuse of these wastes. In this point, the proposed project stands out, as it brings environmental appeal to the study where an application for such waste can …
- Applying gas diffusion electrodes supported on carbon tissue for the treatment of antibiotic contaminated wastewater, BP.IC
Abstract
The contamination of water and wastewater by antibiotics can cause several problems to humans and animal life, since, due to their action as endocrine interferons, they can cause the increase of microbial resistance in aquatic environments, as well as lower efficiency of conventional effluent treatments. To resolve this, electrochemical technology is an efficient alternative, as it has hi…
- Fe/RuO2-TiO2 films supported on carbon felt for norfloxacin degradation by heterogeneous electro-fenton process, BP.PD
Abstract
Treatment of aqueous wates using heterogeneous Electro-Fenton and Photoelectro-Fenton (Heterogeneous-EF/FEF) has recently attracted attention due to its efficiency and potential capability of application in a wide range of pH and catalyst reusability. However, the main challenge of these processes is the synthesis of cathodic materials to be stable in strongly acid pH along with less comp…

- Sodium niobate electrodes decorated with WO3 and CeO2 for degradation of the organophosphate pesticide acephate by advanced oxidative electrochemical processes, BP.PD
Abstract
Brazil has exponentially increased the number of pesticides released for use in Agriculture in recent years. Many of these pesticides are extremely dangerous for our ecosystem. This work aims to develop a viable alternative for the treatment of effluents contaminated with the organophosphate pesticide acephate, using Advanced Oxidative Electrochemical Processes (AOEP). The modification of…
- Advanced oxidation processes based on the in situ activation of oxidants via UVC and solar radiation for the simultaneous elimination of microcontaminants and pathogens, BP.PD
Abstract
The contamination of surface water by contaminants of emerging concern and, more recently, by pathogenic bacteria is increasingly attracting the attention of the scientific community and society to avoid the risk of diseases and the production of superbugs. In this sense, this postdoctoral project aims to study the in situ activation of oxidants (H2O2, S2O82-, HSO5- and HOCl) by irradiati…
- Treatment of wastewater contaminated with endocrine interferences through the application of electrochemical advanced oxidation processes: synergistic effect of different carbon supported cathodes, BP.PD
Abstract
Electrochemical Advanced Oxidation Processes (EAOPs) are promising technologies for environmental remediation. These processes are based on the high oxidation power of hydroxyl radicals. This radical is a strong oxidant with high reactivity to degrade organic pollutants present in liquid effluents. Hydrogen peroxide (H2O2) can be electrogenerated in the system by reducing two oxygen elect…

- Gas diffusion electrode based on carbon modified with benzophenone applied to co-generation of oxidants radicals in a reactor cell, BE.EP.DD
Abstract
Reactor systems can be used for both electrogeneration of perfosphate (anode) and electrogeneration of hydrogen peroxide (cathode), but these systems have been studied separately. The suggested approach would be to study both processes coupled to the same reactor, where the processes would take place simultaneously. Using a boron doped diamond electrode (anode) and a carbon based gaseous …

Abstract
The application of electrochemical advanced oxidation processes (EAOP) in the treatment of gaseous pollutants has becoming a topic of increased interest. In this line, the use of more sustainable technologies for the treatment of toxic volatile organic compounds (VOCs) by combination of an EAOP with absorption technique appears as a very promising strategy. Among EAOP, heterogeneous elect…

- Modified gas diffusion electrodes applied in the degradation of organic pollutants in a flow electrochemical reactor, BE.EP.DD
Abstract
Advanced oxidative processes (POA) are based on the production of hydroxyl radicals (HO*) as oxidizing agents that are capable of degrading organic pollutants into inoculum compounds. One way of generating the hydroxyl radical is by hydrogen peroxide (H2O2). The H2O2 can be produced in high concentrations through the oxygen reduction reaction (ORR) using the gas diffusion electrodes (GDE)…
- Comparative mineralization of mixed antibiotics in synthetic hospital wastewater matrices by electrochemical AOPs using a solar-assisted plant, BE.EP.PD
Abstract
Antibiotics, when administered orally, are usually excreted in the urine and feces, without being metabolized by human and animal bodies, thereby contaminating the sewage discharged from hospitals. In the last decade, electrochemical advanced oxidation processes (EAOPs) have received considerable attention for the removal of these organic compounds from contaminated water However, most of…
- Development of new catalysts for fenton-like processes for endocrine disruptors degradation, BE.EP.DD
Abstract
Advanced Oxidative Processes (AOP) are based on the generation of hydroxyl radicals (HO*) that are capable of degrading organic compounds into harmless compounds. One of the precursors of hydroxyl radicals is hydrogen peroxide (H2O2) which when coupled with the Fenton process provides an increase in the rate of hydroxyl radical formation to achieve greater efficiency in the degradation of…
