Abatement of 1,1,2,2-tetrachloroethane in water by reduction at silver cathode and oxidation at boron doped diamond anode in micro reactors

摘要: Abstract The treatment of aqueous solutions 1,1,2,2-tetrachloroethane was performed by anodic oxidation at boron doped diamond (BDD), cathodic reduction silver and coupled processes. Experiments were in macro micro reactors with an interelectrode distance lower than 100 μm. Drastically higher abatements the chlorinated compound current efficiencies obtained microdevices that, furthermore, allowed to perform electrolyses low cell voltages absence supporting electrolyte. When processes carried out simultaneously microreactor, a abatement pollutants same amount passed charge applied voltage respect uncoupled effect some operative parameters, including flow rate, density, initial concentration pollutant interelectrodic distance, on performances process also studied.
