本研究使用聚甲基丙烯酸甲酯作為擔體乘載普魯士藍，合成一具有高吸附能力之吸附劑，以此模擬水中放射性銫之吸附行為，由於普魯士藍在吸附過程中會釋放微量鐵離子的問題，因此必須進行材料最適化之探討。在本研究中分為兩部分，其一為聚甲基丙烯酸甲酯乘載普魯士藍顆粒的反應參數最適化: 顆粒合成採用懸浮聚合法，以控制變因實驗方法找出各配方及反應條件對顆粒形成的尺寸與幾何形貌的影響性，藉以了解聚合過程中控制顆粒尺寸的控制變因，再根據銫離子移除率、鐵離子洩漏濃度配合田口式品質工程法進行反應參數最適化，並以此決定最適配方及反應條件。其二為吸附行為的研究: 以非放射性銫-133配置原水進行吸附實驗。首先以杯瓶實驗測試普魯士藍-壓克力顆粒之動態及靜態動力學性質，再將顆粒以隨機填充方法於填充床中裝填進行連續吸附實驗，檢視其穿透曲線並以數學模型模擬自來水廠之快濾池配置，用以評估在快濾池進行放射性銫吸附之可行性，最後提供具有放射性銫淨化能力顆粒之製備方法及應用於填充床之操作參數，在突發核災時可做為應對之手段。

　　The main objective in this research, poly (methyl methacrylate) (PMMA) is used as a support medium to load Prussian blue (PB), forming a high performance adsorbent. This adsorbent is used to simulate radioactive cesium (Cs) adsorption behavior in both deionized water and sea water. Since PB decomposes during the adsorption process and releases iron (Fe) ions into water, the optimization of bead performance is described. The first of objectives in this study is the optimization, methodology, and synthesis process for PB-PMMA beads, the effects of variables to PB-PMMA bead performance can be estimated, and then the most suitable reaction conditions and methodology for PB-PMMA bead synthesis determined. The second part of this study is the adsorption behavior of cesium towards the PB-PMMA beads. Non-radioactive 133Cs is used to prepare a standard solution for use in an adsorption experiment. First, a batch experiment is employed for understanding the kinetic properties for Cs removal and Fe leakage. Second, in order to establish the breakthrough curve and comparison with the simulation of rapid filtration in a water plant, a fixed bead adsorption experiment is employed using PB-PMMA beads packed randomly into a column. Third, in order to isolate and remove radioactive Cs from polluted water, the feasibility of using PB-PMMA bead in a rapid filtration method can be evaluated.
