عنوان انگلیسی Removal of 1-naphthol from Water via Photocatalytic Degradation Over N,S-TiO2/ Silica Sulfuric Acid under visible Light
چکیده انگلیسی مقاله Background: Naphthol, one of the naphthalene derivatives, is the most significant industrial chemical. It is widely used in the biochemical processes, production of dyes, and pharmaceutical industries.
Methods: In the present study, N, S-doped TiO2 thin film immobilized on Silica Sulfuric Acid (SSA) glass Microspheres (MS) was investigated as a novel high efficient photocatalyst. We fabricated N, S-doped TiO2 immobilized on SSA using a simple modified sol-gel process. Its photocatalytic activities were then assessed by 1-naphthol solution in the presence of visible light. The physicochemical properties of photocatalyst were characterized using Energy-Dispersive X-ray (EDX), Scanning Electron Microscope (SEM) images, and X-Ray Diffraction (XRD) pattern.
Results: According to the obtained results, the optimal pH, time, concentration, and removal efficiency of 1-naphthol for N, S-doped TiO2 /SSA were 5, 50 min, 25 mg/L, and 92.12%.
Conclusion: The present study confirms the usability of the immobilized N, S-doped TiO2 on SSA glass MS as a novel, effective, and efficient technique for treating wastewater containing 1-naphthol under visible light.
