    Abstract: 本計畫採用台電燃煤底灰作為吸附材料去除水中之氟離子,以期解決含氟廢水排放問題,並使燃煤底灰達到再利用之目標。實驗結果顯示:台電燃煤底灰對氟離子之吸附能力,於酸性(pH=3~5)下有較佳之吸附效果(氟離子去除率為77.9%~70%),且吸附速率相當快。燃煤底灰吸附模式符合Langmuir等溫式,且固液比越大,氟離子去除效果越好。活化處理(酸化)後之燃煤底灰對氟離子吸附能力,約可提高1.5~2倍之吸附容量。燃煤底灰對氟離子吸附容量大致上隨其粒徑之減小而增加。就經濟性而言,成本較活性炭低的燃煤底灰,因具有再利用的價值,適合作為吸附氟離子之吸附劑,值得供電子工廠及半導體業所排放高濃度之氟化物的廢水參考採用。
