             abstract = "The thiadiazolylurea derivative tebuthiuron (TBH) is commonly used 
                         as an herbicide even though it is highly toxic to humans. While 
                         various processes have been proposed for the removal of organic 
                         contaminants of this type from wastewater, electrochemical 
                         degradation has shown particular promise. The aim of the present 
                         study was to investigate the electrochemical degradation of TBH 
                         using anodes comprising boron-doped (5000 and 30000 ppm) diamond 
                         (BDD) films deposited onto Ti substrates operated at current 
                         densities in the range 10-200 mA cm(-2). Both anodes removed TBH 
                         following a similar pseudo first-order reaction kinetics with 
                         k(ap)p close to 3.2 x 10(-2) min(-1). The maximum mineralization 
                         efficiency obtained was 80%. High-pressure liquid chromatography 
                         with UV-VIS detection established that both anodes degraded TBH 
                         via similar intermediates. Ion chromatography revealed that 
                         increasing concentrations of nitrate ions (up to 0.9 ppm) were 
                         formed with increasing current density, while the formation of 
                         nitrite ions was observed with both anodes at current densities >= 
                         150 mA cm(-2). The BDD film prepared at the lower doping level 
                         (5000 ppm) was more efficient in degrading TBH than its more 
                         highly doped counterpart. This unexpected finding may be explained 
                         in terms of the quantity of impurities incorporated into the 
                         diamond lattice during chemical vapor deposition.",
