Kongo kırmızısı (congo red) ve metilen mavisi (methylene blue) boyar maddelerinin elektro-Fenton yöntemi ile çözeltiden uzaklaştırılmasının incelenmesi (PRATİK)
Project no. 23496 · Status: Kapanmış · 2022
Summary
<p>In the content of our project, removal of congo red and methylene blue dyes from solution by electro-Fenton method is tried. Cathode used for this purpose was fabricated out of platinum mesh netting and anode from high purity platinum wire. An eight hour monitorization was performed solution phase at pH 2.5-3.5 range, containing iron (II) sulfate heptahydrate as catalyst and sodium sulfate as electrolyte, where 400 rpm magnetic stirring and dissolved oxygen was provided. Based on the UV-Vis spectrums of the samples stored in Eppendorf tubes, degredation rate of both dyes was observed lower than expected. Among the experimental parameters that are mostly in agreement with the papers in literature related to electro-Fenton method, only cathode surface area was observed not to be big enough. Therefore hydroxyl radical was produced simultaneously at low concentration and dyes were degredated at lower levels. On the other hand, decrease observed in the UV-Vis spectrum of dyes during the 480 minutes monitorization pointed out that even at least a partial success of degradation process by electro-Fenton method was achieved. It’s been concluded that a far more effective degradation will be achieved if the monitorization time was increased from 8 to 12 or 24 hours.</p>
