    Abstract: 本研究利用農業廢棄物椰殼為原料,以硫酸亞鐵為活化劑,製備高孔細活性碳。研究中探討活化劑(FeSO4)含浸濃度的不同及製備條件不同對於活性碳孔隙結構得影響,如表面機、孔徑大小分佈、孔體積、N2吸脫附特性等,並討論活性碳表面結構得不同對於酚溶液吸附效果之差異。由酚溶液的等溫吸附試驗結果,利用Freundlich吸附方程式描述其吸附行為,並探討孔洞特性與吸附行為間之關聯性。研究結果發現,活性碳得表面積和孔隙體積隨著活化劑濃度增加而減少,而表面平均孔徑則會隨之增大,結果顯示含浸劑濃度增加時,會增加活性碳之中孔比例。酚溶液的等溫吸附試驗中,由Freundlich吸附方程式的吸附平衡常數(k)與動力級數(n)得知,k與n值與活性碳表面積大小具有正比之關係,且於酚的吸附試驗中發現以低儂度活化劑所活化的活性碳具有較好的吸附能力與吸附容量。
