Undergraduate internships

re-dispersion of sedimentation sludge

L2IA and LSFC proposal (1st semester 2022)

As sludges are the residue of final stages of industrial processes, be it from petroleum or mining processing or from recycling channels, they are rarely simple systems to analyze and/or to treat......
The objective of this internship project is therefore to study a model sludge formulated from a precipitation of insoluble salts and iron hydroxide, forming aggregates of variable submicron size that can be dispersed in the aqueous phase.

valorization of the biochars resulting from the biomass of the cane of provence

LNER proposal (1st semester 2022)

Reed and Provence cane are invasive species that are regularly cut for the maintenance of facilities, banks, roads ... but also by farmers and municipalities. Generally, this biomass is eliminated by burning, stored in dedicated spaces or transformed into shredded material or compost.

The objective of this internship topic is to answer two questions. The first one is technical and consists in defining their potential application for the retention of strategic metallic contaminants. The second question is scientific and will consist in understanding the mechanisms leading to the retention of these contaminants of interest.

Simulation of the ion adsorption at the liquid/liquid interfaces

LMCT proposal (1st semester 2022)

The recycling of metals is commonly done by liquid-liquid extraction where various ionic metal compounds are selectively transferred from an aqueous phase to an organic phase. The proposed internship aims at describing and understanding the extraction mechanisms occurring at the liquid/liquid interfaces and more particularly the water/oil interfaces such as those involved in the separation chemistry.

The aim of this project is to model these transfer properties using a theoretical approach based on molecular dynamics simulations in an attempt of understanding the transfer mechanisms and predicting the transfer properties of the ions.
