Electrochemical oxidation of para-chlorophenol on Ti/SnO2-PbO2 electrodes: introduction of a parameter for the estimation of their efficiency

The electrocombustion technique has recently been proposed to oxidize nonbiodegradable org. pollutants such as chlorophenol. The authors considered two different types of electrode material: boron doped diamond (BDD) and lead dioxide electrodeposited on Ti/SnO2 substrate and the authors studied differences between them in terms of org. oxidn. efficiency. In the batch system the authors used for the combustion, exptl. parameters - initial concn. of the org. compd., temp. and c.d. supplied to the system - showing that a parameter like the instantaneous current efficiency (ICE) is affected by mass-transfer limitation at the end of the tests. The authors therefore introduce a new parameter not influenced by these problems that can be very effective for the description of electrode efficiency. [on SciFinder (R)]
