Abstract:

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 TiO۲ thin film immobilized on Silica Sulfuric Acid (SSA) glass Microspheres (MS) was investigated as a novel high efficient photocatalyst. We fabricated N, S-doped TiO۲ immobilized on SSA using a simple modified sol-gel process. Its photocatalytic activities were then assessed by ۱-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 ۱-naphthol for N, S-doped TiO۲ /SSA were ۵, ۵۰ min, ۲۵ mg/L, and ۹۲.۱۲%.Conclusion: The present study confirms the usability of the immobilized N, S-doped TiO۲ on SSA glass MS as a novel, effective, and efficient technique for treating wastewater containing ۱-naphthol under visible light.
