本研究探討在高鹽度人工地下水條件下銫在粉碎花崗岩中的遷移與遲滯現象,主要目的在決定是否由批次實驗分析結果所決定之經驗收附模式可以直接用於管柱實驗結果的推估上。在批次實驗中包含收附實驗與脫附實驗,目的是探討銫的收、脫附動力反應。而管柱實驗則包含擴散與平流 (advection) 實驗,希望藉由對突破曲線 (breakthrough curve) 的分析來探討水流速對收、脫附的影響。
實驗結果顯示從批次實驗所求得的參數並不適用於管柱實驗結果的推估。而四種收附模式也不能合適的描述批次實驗的結果。如果要詳盡地描述收附的現象,進一步的研究以決定主要的反應機制是必須的。平流管柱實驗結果的分析中,銫於粉碎花崗岩的收、脫附反應機制可能至少包括兩種速率的反應。
