中文摘要 | 本裝置採用陽極處理與薄膜改質技術,製作奈微米多孔性改質氧化鋁(AAO)過濾膜感測結構,可有效吸附分離溶液重金屬離子。設計化學發光檢測機制整合於立體微流檢測系統,實驗檢測市售彩妝化妝品重金屬含量。採用化學沉積法分別將聚羅丹寧、活性氧化鋁與活性碳三種吸附劑聚合於AAO膜多孔表面與孔洞側壁,形成具多吸附性分離之多孔吸附AAO複合膜,改質AAO複合膜具有良好的孔洞均勻性、高孔隙率、特異吸附性和良好的透水性,能有效提高AAO膜表面吸附與分離金屬離子能力。 |
英文摘要 | The modified nanoporous Anodic aluminum oxide (AAO) as sensing structures for adsorption of heavy metal ions removal from aqueous solution was developed by two-step anodization and surface modification processes The chemiluminescence (CL) reaction of luminol-based mechanism for measuring selected ions concentration was achieved by using a three dimensional stacked centrifugal microfluidic system. The adsorbents of rhodanine monomer, activated alumina and activated carbon were immobilized onto the surface and internal pores of nanoporous AAO template as multi-filtration modified-AAO composite membrane exhibited excellent uniformities, high surface porosity, low nonspecific adsorption and good hydraulic permeability and can be used for enhancing adsorption and separation of heavy metal ions. |
