中文摘要 | 本研究利用硫酸亞鐵活化國內大宗農業廢棄物蔗渣製備活性碳,探討化學性活化 製備過程,如最終活化溫度、含浸活化劑濃度、最終活化時間等變化,對碳化產物之物理及 化學特性的影響,由製備條件之差異探討條件變化對於活性碳之熱裂解產率、含水量、灰份 、pH 值,及活性碳對於酸性染料廢水之去色效果, 由研究結果顯示,製備條件中最終活化 時間對於活性碳物性影響不大,而最終活化溫度及含浸活化劑濃度高低對活性碳之特性與對 酸性染料之吸附性能影響較大,蔗渣經化學性活化所製成的活性碳應用於染料廢水去色有良 好的去色效果。 |
英文摘要 | Activated carbons were prepared by chemical activation process from agricultural wastes (sugarcane bagasse) with iron sulfate (FeSO �� ) as an activating agent at various pyrolysis conditions. The dominated factors, such as final activation temperatures, concentrations of immersing agent and final activation time, affected the characteristics of activated carbons and adsorption performance for acidic dye wastewater were discussed in this investigation. The characteristics of carbon products were evaluated the pH, ash content, moisture content, and dye adsorption properties for preparing high adsorption performance of activated carbon. Based on the results of this study, it was showed that the pyrolysis time of agricultural wastes slightly influenced the characteristics and adsorption performance of final products. However, the characteristics and adsorption properties of final products were significantly affected by pyrolysis temperature and concentration of immersing agent in preparing of activated carbons. It was concluded that high adsorption performance of activated carbons could be prepared from agricultural wastes and it was showed a good adsorption capacity for dye wastewater treatment. |
