New Microporous Polymers for Carbon Dioxide and Toxic Metal Ion Capture

The study concentrates on the synthesis and characterization of a novel series of Microporous polymers via Freidel-crafts alkylation of phenothiazine based polymers. The produced cross-linked polymers will be characterized via several spectroscopic techniques (solid 13C-NMR and FT-IR). Thermal properties will be investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The surface properties and morphology will be studied via scanning electron microscopy (SEM). The cross-linked polymers will be evaluated for their efficacy for carbon dioxide capture and toxic metal ion removal. For carbon dioxide capture; the microporous polymers will go through different reaction conditions in order to achieve best textural features that will consist of high surface area, microporosity, and high adsorption capacity of carbon dioxide with high selectivity compared to methane and nitrogen. for toxic metal ion removal the polymers will be studied under various conditions (pH, Time, Initial concentration, temperature) for their application in the treatment of wastewater samples obtained from different water treatment plants in the eastern province of the Kingdom of Saudi Arabia.
