Abstract:The dyes present in textile e uents have a complex structure and low biodegradability, making it necessary to use e cient treatments such as advanced oxidation processes (AOP). The aim of this study was to compare the e ciency of photo-Fenton (PF) and electro-Fenton (EF) AOPs in the degradation of direct black dye 22 (PD22), de ning the best experimental conditions and evaluating the kinetics and toxicity of the proposed treatments. Initially, for the PF system, using UV-C and sunlight radiation, 99.08% and 99… Show more
