Description of the thesis topic
Elastic stationary phase for the development of original filtration/recovery systems of metallic ions
Thesis attached to Ecole Doctorale des Sciences Chimiques from l'Université de Strasbourg (ED222).
Aims of the thesis : this thesis aims to develop an original and efficient continuous flow process using open cell polymer foams coated with a polyphenolic film of bio-based origin to capture and recover toxic metals
Metallic micropollutants are rejected by chemical, mining, electronics and metallurgical industries. They can accumulate into living organisms and thus lead to health problems. Furthermore, regulations become ever more severe on maximum accepted concentration levels on wastewater. The project ESSENTIAL aims to develop an original and efficient continuous flow process using open cell polymer foams coated with a polyphenolic film of bio-based origin to capture and recover toxic metals. Thanks to its elastic feature, the compression of a polymer foam within a given volume should increase the global specific surface available to adsorb more metallic ions and thus increase the competitiveness of this approach. Furthermore, applying cycle of compression-release of the stationary phase during the adsorption or desorption step should intensify both. This strategy contributes to the sustainable management of natural resources, diversify the metals supply and will offer an original, economically competitive and eco-compatible pollution control alternative using a compressible, recoverable and recyclable filtration material.
The PhD student's tasks:
- Development and characterization of the material coated with a biosourced polyphenolic film (in collaboration with Pr. Loïc Jierry of the Charles Sadron Institute, UPR 22)
- Determination of the adsorption and desorption properties of the metals of interest by the coated material
- Development of the continuous flow process for the treatment of real effluents
- Simulation of flow in the material at the scale of a unit volume (in collaboration with Pr. Dominique Thomas, Dr. Augustin Charvet and Dr. Nathalie Bardin-Monnier from the Reactions and Process Engineering Laboratory, UMR7274)- Development and characterization of the material coated with a biosourced polyphenolic film;
The doctoral student will work at the interface of several disciplines: chemistry, process engineering, materials and modelling.
Profile of candidates:
- Students with a very good background in chemistry, materials chemistry or process engineering, pursuing a Master of Research.
- Proficiency in written and spoken English in order to be able to write reports of results and present them at meetings and conferences
- The multidisciplinary and collaborative context of this project requires that the candidate has a strong motivation, a curiosity to broaden his field of expertise, autonomy and an ability to work in a team with strong constraints to meet deadlines.
