—Substances discharged intobodies of water must be
studied due to possible risk of contamination and consequent
damage to nature and human health.Sucralose is an artificial
sweetener widely used to produce diet food and beverage. Most
of this substance is expelled intact fromthe human body;
therefore, its concentration in rivers and wastewaters is
increasing worldwide. In this work, sucralose degradation was
performed using advanced oxidation processes (AOPs):
peroxidation assisted by ultraviolet radiation (H2O2/UV),
Fenton’s reagent (Fe(II)/H2O2/H+), and photo-Fenton
(Fe(II)/H2O2/H+/UV). Mineralization of the sweetener was
measured usingtotal organic carbon (TOC). In addition, AOPs
were applied to different water matrices, such as ultrapure,
synthetic, and surface waters. Experiments were performed to
evaluate the toxicity of the solution during the degradation
