Degradation of Some Environmental Pollutants by Mg-Doped TiO2 Nanoparticle under UV Light in Aqueous Solution

In this research Mg-doped TiO2 nanopowders were synthesized by the sol–gel method. The Mg-doped TiO2 photo-catalyst was prepared using Titanium tetra-iso propoxide and Magnesium sulfate as the dopant precursors. Rhodamine B, Nonylphenol ethoxylates 6 mol, Pseudoephedrine hydrochlorid, and Nicotine were used to study the photocatalytic performance of the Mg doped TiO2 under UV irradiation. The synthesized samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and Photoluminescence (PL). The photocatalytic degradation shows that after 60, 90, 120, and 120min of irradiation time with UV light, 99%, 98%, 98% and 98% ofRhodamine B, Nonylphenol ethoxylates 6 mol, Pseudoephedrine hydrochloride, and Nicotine were decomposed by Mg-doped TiO2 sample, respectively. In this work, we synthesized Mg-doped TiO2 nanopowders by sol-gel method. This photocatalyst were characterized by XRD, TEM, XPS and PL analysis. After than the photocatalyst was applied for degradation of four pollutants such as Rhodamine B, Nonylphenol ethoxylates 6 mol, Pseudoephedrine hydrochlorid, and Nicotine. The maximum degradation for these pollutants were obtained between 98-99%.
