Summary:	染整工業製程現因節水技術的進步，導致廢水中所含化學成分濃度提高，故常有染整廢水排放無法符合法規標準的困擾。近年有學者利用奈米尺寸的氧化鎢來進行染料吸附的應用，得到相當不錯的效果。本研究是利用溶劑熱法，以氯化鎢和異丙醇為起始劑，在界面活性劑的輔助下，合成出一系列具特殊形貌的結晶性氧化鎢。所得產物利用粉末X-ray繞射儀、掃描式電子顯微鏡、顯微拉曼光譜儀及傅利葉轉換紅外線光譜儀鑑定之。由結果得知，在不同界面活性劑的參與下，其產物型態也差異甚多。如：在span80的作用下其產物形態會隨反應時間增長，由最初的奈米線組成的刺蝟體，轉變成奈米線緊密堆疊的微米板。而tween20則是形成奈米顆粒的聚集體。最後，將產物應用於亞甲藍染料吸附，其最大吸附量高達137.27 mg/g。 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.
