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)]
