The degradation of the AB1 dye by electro-generated species using a BDD electrode was performed. The results were explained by the generation of OH radical, S2O8 in the presence of sulfate, and active halide species in the presence of halide salt. The discoloration rate increases in this order: sulfate, KCl, KBr. In the presence of KCl, the discoloration is affected by the current density, init...
