Cadmium removal by D2EHPA-impregnated granular activated carbon [PDF]
, 2010 碩士本研究利用萃取劑D2EHPA改質粒狀活性碳(GAC)，以提升活性碳吸附金屬的效率。由控制不同實驗參數找出最佳吸附效率的參數值，利用這些參數值進行動力吸附模式、等溫吸附模式模擬與管柱實驗。 批次式吸附實驗結果顯示平衡時間與最佳吸附效率的pH值分別為12小時與pH 7。動力吸附模式模擬結果顯示，改質後的活性碳(DGAC)與GAC在溫度為25℃，pH值為7的條件下，分別吸附濃度為100及200 mg/L鎘金屬溶液，以擬二階反應模式最符合，其線性回歸R2皆在0.995以上。等溫吸附模式的模擬結果顯示，
