Electrolytic treatment of C.I. Acid Orange 7 in aqueous solution using a three-dimensional electrode reactor

Electrochemical pretreatment of heavy oil refinery wastewater using a three-dimensional electrode reactor

“…Some researchers confirmed that GAC was beneficial to not only adsorb pollutants on its large specific surface, but in situ generate strong oxidizing agents (such as hydroxyl radical), which significantly improved pollutant degradation in TDER system [24][25][26]. The results also reveal that the appropriate percentage of PCP was 25% in the combination particle electrodes, which is favorable to improve the COD removal efficiency and reduce the energy consumption.…”

Electrochemical generation of H2O2 using immobilized carbon nanotubes on graphite electrode fed with air: Investigation of operational parameters

“…Therefore, the cathode materials which have high H 2 O 2 production ability are very important for the effective destruction of pollutants [8]. Cathode materials such as graphite [2,25,26], reticulated vitreous carbon [26,27], carbon felt [28][29][30][31][32], activated carbon fiber [14,33] and O 2 -fed carbon polytetrafluoroethylene [23,[34][35][36][37] are most typically employed.…”

Decolorization of C.I. Reactive Orange 4 and Textile Effluents by Electrochemical Oxidation Technique using Silver-Carbon Composite Electrode

“…For untreated effluents (0 min), two peaks are observed at wavelengths of 478 and 605 nm. The appearance of the peak at 478 nm in the visible region corresponds to the azo group, 30 whereas the peak at 605 nm in the visible region corresponds to the anthraquinone group. 13 After 100 min of electrolysis using the Ag 28.5 C 66.5 -PVC 5 electrode with an applied voltage of 10 V in the presence of 1.0 mol L -1 of NaCl as a supporting electrolyte, the previous peaks completely disappeared, proving that the electrochemical oxidation method was able to decolorize all the colored material in the effluents.…”
