1 109/1 水環系 彭晴玉 助理教授 會議論文 發佈 電容去離子對陰離子之選擇性研究 , [109-1] :電容去離子對陰離子之選擇性研究會議論文電容去離子對陰離子之選擇性研究郝康旭; 彭晴玉電容去離子;電吸附選擇性;粒狀活性碳;陰離子;水合半徑電容去離子(Capacitive Deionization, CDI)是深具潛力的低能耗脫鹽技術,透過在兩個電極之間施加電壓移除水溶液中離子。當溶液中存在多種離子時,CDI系統對每種離子的去除率不同,即 CDI 系統對離子之電吸附選擇性不同。本研究使用粒狀活性碳作為電極材料應用於 CDI 系統中,探討四種環境中常見陰離子(Cl-、NO3-、SO42-、H2PO4-)之電吸附選擇性。以 GAC 應用於 CDI 系統中,於單一離子溶液中,Cl-、NO3-、SO42-與 H2PO4-各陰離子之吸附當量分別為 86.0、129.2、146.3、75.3 μN/g;而在混合四種陰離子實驗中,Cl-、NO3-、SO42-與 H2PO4-的吸附當量為 20.5、21.7、51.3、10.1 μN/g,結果與單一離子溶液相符,顯示以 GAC 應用於 CDI 系統對於陰離子的電吸附選擇性為 SO42- > NO3- > Cl- > H2PO4-。電吸附的選擇性與離子價有高度相關,離子價數越高,離子被 CDI 系統電吸附效果越好。於相同離子價的混合離子溶液中,則是以水合半徑(hydrated radius)影響電吸附選擇性,低水合半徑的離子表現出較高的電吸附選擇性。而混合四種陰離子的結果證明了對電吸附選擇性而言,即使Cl-有較小的水合半徑(Cl-: 3.32 Å、SO42-: 3.79 Å),但離子價比水合半徑具有更大的影響力。zh_TW國內無20201127~20201128是TWN第32屆環工年會暨廢水處理技術研討會桃園市,台灣

3 109/1 水環系 彭晴玉 助理教授 會議論文 發佈 天然有機物對電容去離子系統之影響 , [109-1] :天然有機物對電容去離子系統之影響會議論文天然有機物對電容去離子系統之影響王映叡; 彭晴玉電容去離子;腐植酸;Suwannee River 天然有機物;活性碳水資源匱乏已成為全球關注的議題。電容去離子(Capacitive Deionization, CDI)是新興的離子去除技術,具有低能耗、低成本、無二次污染、電極再生容易等優勢,用於去除淡鹹水中之離子深具潛力。CDI 的大多數研究都集中在改善電極性能、開發電極材料或針對無機鹽類,較少有研究探索天然有機物對 CDI 系統的影響。實際的自然水體成份複雜,不僅包含陰陽離子,還包含大量有機物質,有機物質的存在可能會阻塞 CDI 電極,導致 CDI 脫鹽效率下降。本研究主要以兩種有機物質: 腐植酸(HA)與 Suwannee River 天然有機物 (NOM) ,探討在有機物存在下對 CDI 系統脫鹽性能的影響。在含有 HA 或 NOM 的溶液中,導電度的平均去除率從 20.9%分別下降至 16.75%或 15.43%,代表有機物質的存在確實會降低 CDI 系統去除鹽類的效率。本研究進一步觀察先零電壓物理吸附有機物質五小時後,再進行 CDI 電吸附實驗,在第一個循環的電吸附過程中,有機物質會從電極材料中被脫附出來,而在後續的每一個循環的零電壓脫附時,有機物質會再被吸附到電極材料上,顯示有機物質與離子存在競爭關係。zh_TW國內無20201127~20201128是TWN第32屆環工年會暨廢水處理技術研討會桃園市,台灣
