Degradation of diuron in water by electrochemical advanced oxidation in a microreactor: effects of anion contamination on degradation and toxicity

Electrochemical Degradation of Diuron by Anodic Oxidation on a Commercial Ru0.3Ti0.7O2 Anode in a Sulfate Medium

“…In summary, regarding Diuron degradation, these results demonstrate that Diuron can be anodically degraded in MMO. Compared with the studies mentioned in the Introduction section [32][33][34][35][36][37][38], we can infer that our results are inferior in terms of removal efficiency (we achieve removals up to 40% compared with 90% reported in the mentioned studies). Nevertheless, we need to consider that this study proposes using a sulfate medium instead of chloride to assess the feasibility of degrading Diuron, intending to avoid the generation of organochlorines (current ongoing research).…”

“…Khongthom et al [36] studied the Diuron degradation on a graphite anode in a microscale reactor with levels of degradation above 90% for residence times of 100 s. Zhu et al [37] achieved a 100% Diuron degradation on a Co 3 O 4 /graphite composite anode at pH 2.0 and 2 mA cm −2 . Finally, Bumroongsakulsawat et al [38] analyzed the influence of sulfate and nitrate interferences on the Diuron degradation mechanism and toxicity of the final effluent. The researchers observed that both anions reduced the efficacy of Diuron oxidation by scavenging hydroxyl radicals.…”

Potencial de adsorção do nanocompósito híbrido de grafeno magnético para remoção de herbicida diuron

“…O diuron (3-(3,4-diclorofenil)-1,1-dimetilureia) é um herbicida comumente usado em áreas agrícolas e não agrícolas. É quimicamente estável, persistente no ambiente, carcinogênico e genotóxico (Bumroongsakulsawat et al 2020). A molécula de diuron pode ser encontrada no solo, nas águas superficiais e subterrâneas, sendo levemente tóxico para mamíferos e aves, além de moderadamente tóxico para invertebrados aquáticos (Zbair et al 2020).…”
