中文摘要 | 電-芬頓系統為高級氧化技術,其氫氧自由基能以自我循環方式將汙水降解,然系統電性及陰極污廢水處理效率有限而限制其發展。因此,本研究以奈米碳管(CNT)管狀高比表面積結構與導電性基礎,應用氫氧化鉀(KOH)進行表面改質及藉聚偏氟乙烯(PVDF)來穩固成形於陰極極板上,冀提升電-芬頓系統陰極過氧化氫的反應速率及極板電性。實驗藉由線性伏安法、接觸角測量、四點探針量測及掃描式電子顯微鏡(SEM)進行極板在電-芬頓系統之特性量測。結果顯示,經活化後之極板其表面密度再次提高,接觸角下降31 %且過氧化氫(H_2O_2)累積濃度達39μM;亦即由本研究成果可知,CNT-PVDF經KOH活化後具運用於微生物燃料電池極板可行性及研究價值。 |
英文摘要 | Electro-Fenton system is an advanced application technology of oxide, hydroxyl radicals by self-cycle mode to the sewage degradation, but the overall performance of the application by the electricity production efficiency and the cathode sewage wastewater treatment impact. Therefore, carbon nanotubes (CNT) of the tubular structure and high specific surface area conductive base, applied of potassium hydroxide (KOH) by surface modification and polyvinylidene fluoride (PVDF) to stabilize forming the cathode plates, aiming to enhance the electro-Fenton system cathodic reaction rate of hydrogen peroxide and electrical plates. Experiments by linear voltammetry, contact angle measurements, four-point probe measurements and scanning electron microscopy (SEM) were measured characteristics of the cathode plate. The results show that upon activation of the cathode plate whose surface density again increased and the contact angle decreased by 31%, and hydrogen peroxide (H_2O_2) cumulative concentration of 39μM, It is seen from the present studies, CNT-PVDF after the activation of KOH plates can be used with the feasibility of microbial fuel cells. |
