中文摘要 | 先前研究 (1,2) 指出,染料生物處理所 產生之降解中間物具有電子梭 (ESs) 催化 特性,可更有效刺激胞外電子傳遞效率, 同時亦可促進染料廢水的脫色作用,並具 有電能回收之可行性角色,更指出構成電 子梭或具有生物可分解性的關鍵,主要在 於化合物官能基結構上,而且在電子轉移 機制上扮演著極重要的角色 (2) 。本研究以 此為基礎,將先前研究發現之各種中間物 (例如:偶氮染料降解之相關 2AP, 4AP, 12db, 14db, b12d, b14d, 1A2N, 4A1N)及非 偶氮硫堇類染料(如:Thionine、Azure A、 Azure C 等)加入微生物燃料電池 (MFCs) 中作整體性地進行電子轉移研究,亦以 MFC 為手段來運用電子梭提升生物產電效 能,同時對生物降解之促進進行系統性結 論性初探。因此本研究更將探討到染料具 電子梭功能之可能結構,化學結構對生物 分解性之相關影響,及電子梭能否能促進 生物降解相關問題,再以上述三點來討論 適合 MFC 之電子梭結構,並探討出最具效 益及環境友善之 MFC 操作模式。 |
英文摘要 | Abstract: Prior studies indicated that degraded intermediates of biotreatment can play a crucial role as electron shuttles (ESs) to autocatalyze exogenous electron transport of pollutant degradation. They can simultaneously stimulate dye biodecolorization and electric energy recycling. This study showed that the electron-mediating characteristics of these intermediates were strongly dependent upon their functional groups present in the chemical structures. We evaluated the potential of electron-transporting characteristics of these chemicals (e.g., 2AP, 4AP, 12db, 14db, b12d, b14d, 1A2N, 4A1N) and thioninebased textile dyes (i.e., thionine, azure A, azure C) for practical applications. We observed that using microbial fuel cell (MFC) as operation strategy could effectively augment bioelectricity-generating capabilities for pollutant degradation. We also observed feasible chemical structures of ESs for pollutant degradation, deciphering-associated issues of ES-enhanced biotreatment. We concluded that ES structures can stimulate environmentally-friendly MFCbased bioremediation. |
