• 中文摘要： 本文研究芥黃及紅色染料混合水溶液在粒狀活性碳上之吸附與脫附行為, 在批式實驗中, 改變不同起始染料之濃度, 以探討其等溫吸附線; 在管柱實驗中, 改變不同入料之濃度, 以探討其貫穿與脫附曲線。雙成份之等溫吸附線最適以Fritz與Schlunder模式表示之。合諧條件配合Fritz-Schlunder模式可用以構建成份路徑圖, 而中間層之組成濃度可由成份路徑圖中讀出。根據非線性波傳遞理論, 本文推導出能預測貫穿與脫附曲線之簡單方程式。
• 英文摘要： The adsorption and desorption behaviors of mustard yellow and red binary dye mixtures by granular activated carbon from aqueous solution were studied. Batch tests with different initial dye concentrations were performed to determine the adsorption isotherms while column tests with different feed dye compositions were performed to measure the breakthrough and desorption curves. The Fritz and Schlunder model was found to best fit the binary adsorption isotherm data. The coherence condition incorporated with the Fritz-Schlunder isotherm model was used to construct the composition path diagram with which the intermediate- zone composition could be determined. Simple equations were derived based on the non-linear wave propagation theory to predict the breakthrough and desorption curves.
