All relevant results will be published in international journals and presented at national and international conferences. In addition, if these materials perform well, the patentability of any new results will be considered before any public disclosure.
Pharmaceutical wastes represent one of the emerging pollutants that endanger human health because of their toxicity and resistance to conventional treatment techniques. As a result, efforts to find effective remediation techniques to fully remove this new class of pollutants from the environment and water have turned to Advanced Oxidation Processes (AOPs), of which heterogeneous catalysis using iron oxides (Magnetite for instance) are a subset  .
Activated carbon (AC), a general adsorbent for removal of wide range of pollutants from water, has some important advantages such as special structure and high adsorption capacity which have highlighted the AC application in many treatment plants  .
Mixing the 2 materials, Magnetite and activated carbon, into a mixed nanocomposite represent a promising solution for the elimination of Pharmaceutical Pollutants.
In this study 2 types of activated carbons will be studied, a synthetic one from agricultural waste and another commercial AC. In situ synthesis of the nanocomposite based on Fe3O4 nanoparticles and activated carbon will be conducted  . The mixed material will be used to study the kinetics of oxidation of Amoxicillin via 2 oxidative systems: Sulfate radicals and Hydroxyl radicals mediated oxidation of Amoxicillin. Characterization of the solid materials .
Selected applicant will boost her/his knowledge in the field of heterogeneous catalysis. She/He will work on several techniques for solid characterization and liquid analysis: ex: Raman, FTIR, BET-BJH, and UV-Vis.
