             abstract = "In this work, the electrolysis of Reactive Blue 19 (RB-19, a toxic 
                         textile dye with a high half-life) using a highly non-commercial 
                         boron-doped diamond film on titanium substrate (BDD/Ti) was 
                         studied. The BDD film with a B/C ratio of 15,000 ppm, a doping 
                         level around 1019 cm-3 and higher content of sp3 (diamond) than 
                         sp2 (graphite) was produced with high quality and stability. Under 
                         appropriate conditions, the electrode promoted complete 
                         decolorization of RB-19, together with 99% of TOC removal and a 
                         significant decrease in toxicity against V. fischeri. Furthermore, 
                         benzene rings, aromatic amines and naphthalene could be removed 
                         also during the electrodegradation. The decay in dye concentration 
                         followed pseudo-first order kinetics and the values of the 
                         apparent rate constant increased with increasing current density 
                         applied. In addition, the main intermediates compounds of RB-19 
                         degradation on BDD/Ti based on HPLC-MS analysis were 
                         amino-anthraquinone, tautomers keto-enolic, hydroquinone and 
                         benzoquinone, benzoic acid, phenol and acid aliphatic, such as 
                         oxalic acid. It is concluded that electrochemical oxidation using 
                         a BDD/Ti anode represents a satisfactorily method for the removal 
                         of RB-19 in aqueous solutions.",
