Three different advanced oxidation processes, electrochemical oxidation (EO), electro-Fenton (EF) and photoelectro-Fenton (PEF) were tested for the treatment of individual and mixed solutions of Bismark Brown G, Bismark Brown R and Brown DGI dyes. The experiments were performed in a 500 mL stirred u...
