摘要

This paper aims at investigating the stainless steel 304L (SS304L), 316 (SS316) and titanium electrodes used as working electrode carrying out decolorization of Rhodamine B (Rh B) by Electro-Fenton method. In the dual-cell Electro-Fenton system, the decolorization of Rh B was compared by three different cathodes sequentially via the adjusted parameter of operating factors including working potential, initial pH, Fe^(2+) concentration, supporting electrolyte concentration. The results indicate that the decolorization rate of Rh B was greatest in the case of SS316 and the decolorization approached 64.7% under the suitable condition after 30 min.

隨者科技不斷進步人類開發許多的商業染料，在使用染料過程常有大量有色廢水產生；因此，如何有效處理這些有色廢水為大家所關注之議題。本研究利用304不銹鋼（SS304L）、316不銹鋼（SS316）和鈦（Ti）電極，應用電芬頓（Electro-Fenton）法觀察系統脫色Rh B（Rhodamine B）染料之效能。實驗藉由電芬頓法進行參數調整，包含：工作電壓、酸鹼值（pH值）、支持電解質濃度和亞鐵離子（Fe^(2+)）濃度；觀察在這三種電極之電芬頓系統脫色Rh B染料之效益。結果顯示，SS316不銹鋼電極的脫色性能為這三種電極中之最佳，其脫色效率在系統運行30分鐘後可達64.7%。
