核能電廠低放射性廢棄物(low-level radioactive waste)中來自於冷卻水與廢水除礦器之廢離子交換樹脂，需透過固化焚化等方法安定化後方可進行最終處置。早期台灣以水泥固化法進行處理，然而鑒於長期貯存後水泥固化體有產生膨脹龜裂之虞，自1987年予以脫水暫存，至今全部核電廠加總已有逾1,6000桶(55加侖)脫水樹脂待處理。
為解決各核電廠積貯廢樹脂的困擾，尋求一適當處理技術乃當務之急。目前廢樹脂的處理方法分為三大類：固化法、乾式氧化法、濕式氧化法。本研究將以濕式氧化法中的電芬頓(electro-Fenton)技術氧化分解離子交換樹脂，探討變因包括：樹脂負載量、初始酸鹼值、過氧化氫速率與劑量、亞鐵濃度、外加電流以及亞鐵來源。結果顯示，因氧化劑加入迅速降低溶液酸鹼值，起始pH值對樹脂氧化分解影響不大，electro-Fenton程序在最佳操作條件為40g/L resin loading、20 mM FeSO4、pHi = 2、50 ％ H2O2 = 240 ml(約3400 mM)、H2O2 flow rate =1.2 ml/min、I = 1 A，得樹脂分解率和礦化率皆> 95％。以最佳操作條件進行官能基脫除機制的探討，陰離子交換樹脂相較陽離子交換樹脂不易被分解，並且測試觸媒重複使用性，以及電氯氧化法處理陰離子交換樹脂氧化分解釋出氨氮之可行性。

The ion-exchange resin (IER) is commonly used in nuclear power plant to purify the cooling water and remove radioactive elements. Cementation is a conventional process to treat the spent resin in Taiwan. Swelling of resin by ion-exchanging with calcium ions in the concrete destroyed the container after a long-term storage. This work used electro-Fenton to dissolve the IER at an initial temperature of 85℃. Effectiveness of IER oxidative decompostion was then evaluated by varying the IER loading, the pHi of the solution, the flow rate of H2O2, the dosage of H2O2, the electrical current, ferrous ion concentration and ferrous ion type. Experimental results revealed that the pHi (1.0-3.0) did not play a vital role in ultimate IER removal. IER treated by electro-Fenton was eventually optimized with 1.2 ml/min H2O2, 240 ml of 50 % H2O2, 20 mM FeSO4 at constant current 1 A as treating 40 g/L resin. The decomposition of cationic resin is easier than the anionic resin. After adding 3 times, the IERr and TOCr are near 90 %. After oxidative decomposition of resin, electrochemical oxidation with chloride is feasible.
