| Summary: | 碩士 === 國立高雄大學 === 應用化學系碩士班 === 102 === The treatment of waste-water has been attracted much research attention in the past few years. Adsorption is one more economical and efficient method for water purification. Recently, tungsten oxide (WO3) has attracted attention of its unique adsorptive property.
In this research, WO3-WO3‧0.33H2O with different shapes have been synthesized with a nonionic surfactant by solvothermal method. The products have been characterized by using XRD, SEM, FT-IR and Raman. By controlling the surfactant in the precursor solution or changing the reaction time, the product was changed from urchin-like WO3 to plate-like WO3-WO3‧0.33H2O. The surfactant played an important role in the growth of WO3-WO3‧0.33H2O. The adsorption ability of WO3-WO3‧0.33H2O has also been investigated. The results showed the WO3-WO3‧0.33H2O nanowires with high surface area (158.69 m2/g) and great adsorption ability (137.27 mg/g) were obtained. Tungsten oxide can be as a viable and excellent water treatment material to purify wastewater.
