OFFER DESCRIPTION

Endocrine Disruptors (EDs) are a major concern because they are present in all environmental compartments. In parallel with the actions aimed at eventually replacing these pollutants, it appears necessary to reduce the short- and medium-term risks for the environment and health by destroying these EDs.This is the objective of the PERTURB'EAU project funded by Région Centre – Val de Loire and coordinated by GREMI.

Among the treatment processes of pollutants in wastewater, Advanced Oxidation Processes (AOPs) are studied for many years. The interest of these processes is to allow the production of oxidizing species such as HO●, H2O2, O3... at room temperature and atmospheric pressure. These oxidizing species can react effectively with many organic molecules (pharmaceutical, phytosanitary, etc.) present in water. Among POAs, electrochemical methods [1], ozonation [2], UV light in photocatalytic oxidation or Fenton and Fenton-like photo processes [3] are particularly studied.

GREMI develops plasma sources for the treatment of organic pollutants present in water. Indeed, among AOPs, non-thermal plasmas (NTPs) have the advantage of coupling different processes (ozonation, peroxination, photolysis, etc.) for the production of oxidizing species. NTPs can produce highly reactive species (OH, 1O2, O2−...) with short life-time without external addition of oxidants. NTPs have already been used for the treatment of many compounds such as pharmaceutical residues [4-8] or phytosanitary [9].

 

Thus, the objective of the PERTURB'EAU project is to allow the industrial development of the plasma source for the degradation for the selected EDs (single-component and multi-component) and tested for a greater number of compounds at the end of the project.

The work to be carried out for this postdoctoral position will focus on the identification of the experimental parameters to be implemented with the "plasma" reactor for the treatment of the target molecules, molecule by molecule then with mixtures of the target molecules to study the effectiveness of the treatment on the different pollutants and then on "cocktail" solutions, respectively. This work will allow to achieve a better understanding of the chemical processes involved in the treatment and the mechanisms responsible for the degradation of the target molecules by comparing the experimental results with the numerical simulations that will also be studied in parallel [10].

The effects of the experimental parameters (energy orpower dissipated in the discharge, electrical parameters, composition of the working gas...) on the formation of chemically active species (O3,H2O2,HO, etc ) and on the degradation of selected EDs representative of the major families of Eds molecules will be carried out.

Physico-chemical diagnostics by LC-MS, UV-vis spectroscopy, pH, conductivity, Total Organic Carbon, BOD5, etc. and electrical diagnostics will be performed to evaluate the performance of the process.
