Title of thesis project : Interactions between metallic nanoparticles, traces elements and bacterial biofilm in Wetland soil

Supervisor : Mathieu Pedrot et Aline Dia

Transfert of engineering contaminant

Interaction metals - organic molecules

Metallic nanoparticles engineering

Chromatography, spectrometry, fluorescence, scattering

Research Areas

Chemical oceanography



Analytical chemistry

Thesis Project

In this project we study the behavior of the iron nanoparticles in soil environment. We focus on three aspects. (1) The behavior of trace elements within solid phase of the wetland soil. (2) The interactions between iron nanoparticles, metallic traces elements and the dissolved organic matter. (3) The impact of nanoparticles on the trasnfer of metallic trace elements in a bacterial biofilm.
