本研究以二苯甲醯過氧化物（BPO）為起始劑活化聚對苯二甲酸乙二酯（PET）纖維表面，再以丙烯酸（AAc）為單體行接枝聚合反應製備羧基型離子交換材（carboxyl ion-exchanger）。首先改變接枝參數，探討不同接枝條件對PET吸附材接枝成效之影響，選擇最適接枝參數製備PET吸附材，於不同條件進行吸附試驗，探討羧基型吸附材對銅離子吸附效能及行為。最後選擇適當的脫附劑討論銅離子脫附回收成效及PET吸附材再生耐用性，並以模擬廢水和實廠廢水，評估本研究製備之吸附材應用於廢水處理之可行性。
實驗結果顯示添加1 M丙烯酸單體、以0.1 M硫酸提高0.002 M BPO催化能力、接枝時間4 hr、接枝溫度80oC為最適接枝條件，製備之PET羧基型吸附材最大接枝率為12%。由銅離子吸附去除實驗結果顯示，pH＝4、反應吸附時間60分鐘，羧基型吸附材可有效將50 mg/L銅溶液處理達放流水法規標準3 mg/L以下，其吸附量約達20 mg-Cu/g-polymer。另外，在脫附試驗中，得知HNO3為最適脫附劑，於濃度0.01 N、脫附時間1小時，可得 95%以上銅脫附率，且經脫附的吸附材繼續進行二次吸附，其吸附量上升至27.4 mg-Cu/g-polymer，經五批次吸/脫附實驗，仍有95%吸附效果，顯示其再生特性良好。此外，PET吸附材對模擬廢水中重金屬選擇性吸附效果依序為Pb2+＞Cu2+＞Ni2+，將其應用於實廠含銅電鍍廢水下，可有效吸附回收銅，其吸附量達0.37 mmol-Cu/g-polymer，因此PET羧基型吸附材深具應用潛力。

The surface modification of PET fiber in this study was done by Benqzoyl peroxide activation and acrylic acid grafting. Acrylic acid monomer was grafted for the preparation of carboxyl type ion-exchange material. To exam the influence of different operating parameters on the PET adsorption material grafting effect; first of all, choose the optimal grafting parameter to prepare PET adsorption material, and carry out the adsorption experiments under different conditions to exam carboxyl-type adsorption of copper ion adsorption material performance and behavior. Lastly, select the appropriate desorption agent to discuss the effectiveness of copper ion desorption, recycling adsorption and durability of adsorption material. Moreover, simulations of wastewater and plant wastewater were used to evaluate the feasibility of the prepared adsorption materials.
The results show that optimal grafting conditions are with additions of 1M acrylic monomers, 0.1 M sulfuric acid to enhance the catalyzing capacity of 0.002 M BPO, grafting time of 4 hours and grafting temperature of 80oC. The best graft percentage of prepared carboxyl-type adsorption material is 12%. The results from copper ions removal experiment shows that when pH = 4 and adsorption time of 60 minutes, carboxyl adsorptive material can effectively treat copper solution from originally 50mg/L to under the regulatory standards of 3 mg/L, the adsorption amount is about 20 mg-Cu /g-polymer. In addition, obtaining from the desorption experiment, the optimal agent is HNO3, and at the concentration of 0.01N and desorption time of 1 hour, the copper desorption rate can reach more than 95%. Moreover, when continued with second adsorption, the adsorption capacity increased to 27.4 mg-Cu/g-polymer. After five batches of adsorption and desorption experiments, the adsorption effect still remains over 95%, which shows a good quality of regeneration property.
Furthermore, the adsorption selectivity of PET material to heavy metals in wastewater is Pb2+> Cu2+> Ni2+. When applied to copper electroplating wastewater, copper can be effectively adsorbed and recovered. The adsorption capacity is up to 0.37 mmol-Cu/g-polymer, Hence PET carboxyl-type adsorption material has a great potential for heavy metal recovery application.
