• 中文摘要： 本研究乃探討粒狀活性碳吸附對硝基酚/酚,對氯酚/酚及對氯酚/對硝基酚的吸附平衡實驗,以評估活性碳的吸附能力以及相關吸附平衡模式如Langmuir競爭吸附模式,extended three- parameter吸附模式,理想吸附溶液理論(IAS)及其修正模式(MIAS)之適用性。由實驗結果得知雙成分酚類在活性碳上之吸附平衡會受到相當顯著的相互干擾; 理想吸附溶液理論模式可適用於本實驗之雙成分酚類競爭吸附,而其修正模式可以減少實驗值與計算值之誤差。活性碳吸附能力之了解可提供正確的雙成分吸附平衡行為,作為設計活性碳吸附床體去除廢水中酚類汙染物之基礎。
• 英文摘要： A series of equilibrium experiments have been conducted to assess the capacity of granular activated carbon (GAC) to adsorb three bisolute contaminants of phenols including p-nitrophenol/phenol, p- chlorophenol/phenol and p-chlorophenol/p-nitrophenol. The observed equilibrium data are analyzed and compared with four existing models, i.e., Langmuir competitive model, extended three-parameter isotherm, ideal adsorbed solution theory and modified ideal adsorbed solution theory. The mutual interferences of phenolic adsorption onto GAC are prominent by experimental observation and the bisolute adsorption isotherm curves can be represented by ideal adsorbed solution theory for all three binary phenolic mixtures. Furthermore, modified ideal adsorbed solution theory can reduce the deviations between the experimental and calculated values. The determination of the sorbent capacity will offer the accurate description of bisolute equilibrium behavior for designing the activated carbon adsorber to remove phenol pollutants from wastewater.
