Academic:I am Titular Professor in Inorganic chemistry at University Cheikh Anta Diop and coordinator of the West African Green Chemistry Institute.Research:I am mainly researching new Organno-fonctional modified clays which are are very important for improving the potential application of natural clays, known to have a low cation exchange capacity, as fillers or adsorbent. In this study we aimed to intercalate in clay minerals from Senegal shift basis, and also modified its surface by coating with 3-mercaptopropyltrimethoxysilane (3-MPTMS), tetraethoxysilane (TEOS), 3-aminopropyltriethoxysilane (3-APTES), 3-cyanopropyltriethoxysilane (3-CPTES), octyltriethoxysilane (OTES) and hexadecyltrimethyl ammonium and other surfactant. The natural clay and organo functionalized clay will be investigated as absorbents for removal of heavy metals (such as Cu2+, Hg2+, Cd2+ and Pb2+ etc¦) from aqueous solution. XRD, FT-IR, SEM, TG-ATG and 13C Mas NMR spectroscopy will also be used to characterize the modified organo-clay.In an other hand, we studied inorganic compounds including main group elements and carboxylate, oxoanions or shift basis ligands. The compounds are fully characterized using: Mossbauer, infrared, Raman, RMN spectroscopies and X ray diffraction. The main goal in this topic is to obtain biologically active compounds that can be used in agriculture.
