Offer Description
Over 300 million tons of plastic are produced yearly, with about 13 million tons being released into rivers and oceans. The occurrence of micro- and nano-sized plastic (MPs and NPs) debris in marine and freshwater bodies and its potential impact on aquatic life have recently become a major concern.
While efficient NPs removal technologies remain underdeveloped, Advanced Oxidation Processes (AOPs) represent attractive technologies for NPs degradation. The objective of this PhD thesis project is to evaluate and compare the performances of different homogeneous AOPs, with respect to the degradation of mono- and polydispersed calibrated nanoparticles (NPs).
The PhD candidate will investigate the use of H2O2, iron complexes and peroxymono- and di-sulfate (PMS and PDS) with or without UV-visible light. In each of the tested AOPs, the main tasks will be to identify the radical species involved, to measure the kinetics of NPs removal and to propose a plausible mechanism for the degradation. In addition, during the processes the total organic carbon (TOC) concentration will be followed and the degradation products will be analyzed by liquid chromatography or ion chromatography coupled to mass spectrometry (HPLC-MS & IC-MS). The PhD candidate will also study the degradation of NPs in natural aquatic environments (surface water and wastewater matrices) to evaluate the effect of additives and natural constituents on the degradation of NPs.
This PhD thesis is part of a 4-year collaborative research project funded by the French research agency (ANR). It will take place mainly at the institute of chemistry of Clermont Ferrand (ICCF, UMR 6296) in the photochemistry research team.
