中文摘要 | 煉鋼廢棄物中之轉爐石其富含Fe²+,可應用來催化雙氧水以啟動費頓反應,進而產生氫氧自由基來礦化有機污染物,費頓反應後所產生之Fe³+可藉由紫外光的照射而轉換成Fe²+,如此便可持續催化雙氧水,且紫外光亦可分解雙氧水以產生氫氧自由基,進而提升有機物礦化的效率,本實驗便利用轉爐石於UV/H₂O₂的存在下以礦化水溶液中的聚乙烯醇,實驗發現在pH=2.5、UV光強度為120μW/平方公分,雙氧水及轉爐石添加量分別為2.49×10¯⁴mol /min-L及25g/L時,於90分鐘之反應時間,對PEG可達79.5%的最佳礦化效率,並將此礦化效率以動力學的方式加以描述。 |
英文摘要 | This study evaluated the performance of the photo-Fenton reaction when it was initiated using UV/H₂O₂ with steel waste and basic oxygen furnace slag (BOF slag), here called the UV/H₂O₂/BOF slag process, in order to decompose polyethylene glycol (PEG) in aqueous solution. The concentration of total organic carbon (TOC) was chosen as a mineralization index of the decomposition of PEG in the UV/H₂O₂/BOF slag process. A first-order kinetic model with respect to TOC was appropriately adopted to represent the mineralization of PEG in the UV/H₂O₂/BOF slag process. The experimental results obtained in this study suggest that dosages with 2.49×10¯⁴ mol/min-L H₂O₂ and 25 g/L BOF slag loading in a solution at pH=2.5 with 120 μW/cm² UV provided the optimal operation conditions for the mineralization of PEG, yielding 79.5% mineralization efficiency after 90 min of reaction time. |
