Abstract: The current doctoral project responds to the necessity of developing sustainable treatment technologies to deal with the recalcitrant and non-biodegradable pollutants from polluted waters. This will be addressed by developing advanced functional nanomaterials for the efficient and cost-effective treatment of recalcitrant pollutants from pharmaceutical effluents and the study of the involved mechanisms. The project will cover the following tasks: 1. Fabrication of various advanced functional materials such as the composites of biochar with catalytic materials (such as CuO and zero-valent iron nanoparticles) using facile and green methods. The prepared nanomaterials will be then characterized using various techniques such as X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FE-SEM), N2 adsorption-desorption (BET), Fourier Transform Infrared spectroscopy (FTIR), and Zeta potential measurements, etc. 2. Application of the prepared catalytic materials for the activation of oxidation agents (such as persulphate, H2O2, etc.) for the degradation of recalcitrant organic compounds, such as pharmaceuticals. For each type of nanomaterials, the effect of the influencing parameters (e.g., pH, nanomaterials dosage, contact time, temperature, etc.) will be investigated to obtain the optimal conditions. The degradation mechanism and pathways will be studied by the scavenging experiments and HPLC-MS, respectively. 3. Finally, the synthesized nanomaterials will be used to fabricate the membrane structures with enhanced properties such as water permeability, and porosity. This membrane can not only be used for filtration but also react with oxidation agents to prevent fouling.
