Removal of o-nitrophenol from water by electrochemical degradation using a lead oxide/titanium modified electrode

Preparation and characterization of Ti/SnO2–Sb2O3–Nb2O5/PbO2 thin film as electrode material for the degradation of phenol

“…Such observation indicates that the catalytic activity of the Ti/SnO 2 -Sb 2 O 3 -Nb 2 O 5 /PbO 2 modified electrode can be improved. The removal efficiency could reach 97.2% when 21.3 g/L chloride was added to the solution as the electrogenerated Cl 2 and ClO − ions might play a major role in the electrocatalytic oxidation of phenol [19].…”

“…With more research in applying PbO 2 electrode to the field of water processing, the understanding and knowledge of this type of electrode has become more thorough. A lead oxide/titanium modified electrode has been developed for the efficient removal of o-nitrophenol from aqueous solutions by electrochemical oxidation [19]. Samet using different metal substrates (Ti, Ta, and Pb) with varying composition of electrolysis baths [21].…”

Synthesis of magnetically recyclable spinel ferrite (MFe2O4, M = Zn, Co, Mn) nanocrystals engineered by sol gel-hydrothermal technology: High catalytic performances for nitroarenes reduction

“…Therefore, many researchers are appointed to develop environmental and clean techniques for the removal of such pollutants from industrial waste water. Many redox processes have been managed for the removal of nitroaromatics such as catalytic moist air oxidation [5], photo-catalytic degradation [6,7], electrochemical processes [8][9][10], hydrogenation reactions [11,12], etc. An important way to remove nitroaromatics and to get the maximum benefit is to carry out their reduction to aminoaromatics.…”

Kinetic Study of the Electrochemical Oxidation of Methylene Blue with Pt Electrode

“…3). MVB is also the main product of the nucleophile attack of MB + by OH - [26,27]. The addition of acetone at the end the of electrolysis dissolves the dark precipitate and returns the slight black solution blue (λ max : 610 nm).…”
