本研究探討奈米碳管(Carbon nanotubes, CNTs)與TiO2材料處理水中苯乙烯(Styrene, SM)、正丁苯(N-butylbenzene, nBB)及雙酚A(Bisphenol A, BPA)之可行性。在第一階段中，CNTs分別經H2SO4、HNO3、NaOCl與熱處理(H-CNT)改質後進行批次吸附實驗，結果顯示CNT(NaOCl)對SM、H-CNT對BPA與nBB有較佳吸附量，在最佳操作條件下，SM、BPA、nBB平衡吸附量分別為129.67、86.43、14.29 mg/g，去除效率分別為52、94、84%，均較粒狀活性碳與甲殼素(Chitosan)佳。水質環境實驗中，BPA於pH大於9後吸附效果急遽降低，而有機污染物的吸附於低溫條件較佳。經動力模式分析，這三種污染物的吸附皆屬於擴散作用。經等溫吸附分析，此吸附反應較符合單層吸附；透過熱力學參數計算，三種物質的吸附皆為自發反應，且固液介面親和力良好，有利吸附反應。
Carbon nanotubes (CNTs) were employed as adsorbent to study the treatment of styrene(SM), n-butylbenzene(nBB) and bisphenol A(BPA) in aqueous solutions. For enhancing adsorption capacities of these compounds, CNTs were oxidized by H2SO4, HNO3 and NaOCl or pretreated by heat at 400 ºC. The NaOCl-oxidized CNTs showed the best performance on SM while the heat-pretreated CNTs showed the best performance on nBB and BPA. Adsorption amounts of SM, nBB and BPA on modified CNTs were 129.67, 86.43, 14.29 mg/g, displaying better performance than granular activated carbon and chitosan. Adsorption amounts of SM, nBB and BPA increased with solution ionic strength but those of BPA decreased with solution pH between 9 and 12. Thermodynamic studies indicated that adsorption of SM, nBB and BPA on modified CNTs are all spontaneous and exothermic reactions.
After adsorption studies, the CNT-based TiO2 photocatalysts been prepared by the sol-gel method, and remove the pollutants with UV light support. The NaOCl-oxidized CNT-based TiO2 showed the best performance on SM and nBB, and the HNO3-oxidized CNT-based TiO2 appeared the superior performance on BPA. The removal efficiencies of SM, nBB and BPA on CNT-based TiO2 photocatalysts were 80.6、89.5、93.9%, showing better performance than non-CNT-based TiO2 and P25.
The modified CNTs possess good adsorption performance while the CNT-based TiO2 have good photodegradation performance for SM, nBB and BPA in aqueous solutions. As a result, they are promising for controlling these compounds in wastewater treatment.
