Performance of carbon aerogels particle electrodes for the aqueous phase electro-catalytic oxidation of simulated phenol wastewaters

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

“…Previous studies have demonstrated that AEOPs provide many advantages such as environmental-friendliness, high efficiency in organic degradation, simple reactor structure, and are easy to operate and control [7]. In particular, the electrochemical technologies based on three-dimensional electrode have been attracting much attention for the treatment of various wastewaters, including simulated phenol wastewaters [8], paper mill wastewater [9], landfill leachate [10] and dye wastewater [11,12]. Three-dimensional electrode was originated by means of loading regular or random particle electrode materials between two-dimensional electrodes [8].…”

Three-dimensional electrode was originated by means of loading regular or random particle electrode materials between two-dimensional electrodes [8]. Particle electrode materials (such as activated carbon, carbon aerogel, and graphite particles), in light of their large specific surface area and high electro-activity, contribute to increase the mass transfer coefficient and reduce energy consumption [11,13,14].…”

Kinetics of electrooxidation of phenol on polycrystalline platinum

“…These results clearly indicate that the PhER rates are dramatically slower in highly alkaline NaOH solution than those derived in strongly acidic sulphuric acid medium. The above is most likely the result of restrained formation of the phenoxy radical in addition to the limited extent of phenol adsorption on the Pt surface being in contact with alkaline medium (due to extended Pt surface coverage by OH -ions, as compared to that of SO 4 2-/HSO 4 -in sulphuric acid at the examined potential range) 4, 10 . In addition, the C dl parameter exhibited similar behaviour (signifi cant oscillation over the studied potential range) to that observed above in H 2 SO 4 .…”

Continuous multi-cell electrochemical reactor for pollutant oxidation

“…This trend is similar to that of the COD variation with time in a batch reactor. and Koparal, 2006;Lv et al, 2009). As the organic acids were consumed along cells, the pH value increased gradually.…”
