The excessive use of organic pollutants like dyes, which enter the water environment, has led to a significant environmental problem. Finding an efficient method degrade these is urgent due their detrimental effects on aquatic organisms and human health. Carbon-based catalysts are emerging as highly promising alternatives metal in Fenton-like systems. They serve persulfate activators, effectively eliminating recalcitrant from wastewater. In this study, iron-loaded carbon black (Fe-CB) was synthesized tire waste using chemical vapor deposition (CVD). Fe-CB exhibited high efficiency activator peroxydisulfate (PDS), facilitating effective degradation mineralization rhodamine B (RhB) water. A batch experiment series characterization were conducted study morphology, composition, stability, catalytic activity system. results showed that, at circumneutral pH, 20 mg L

Roles and mechanisms of carbonaceous materials in advanced oxidation coupling processes for degradation organic pollutants in wastewater: a review

Biochar, Год журнала: 2023, Номер 5(1)

Опубликована: Дек. 8, 2023

Abstract The widespread organic pollutants in wastewater are one of the global environmental problems. Advanced oxidation processes (AOPs) widely used because their characteristics high efficiency and strong oxidation. However, AOPs may have some defects, such as incomplete mineralization generation toxic by-products during degradation process, thus it is essential to seek efficient green treatment technologies. Coupling different or other beneficial for reduces ecological risks environment. It worth noting that carbonaceous materials (CMs) received attention application water by advanced coupling (C-AOPs) due excellent physicochemical properties recent years. behaviors mechanisms C-AOPs based on CMs still unknown. Therefore, comprehensively summarize research progress. In this review, applications were reviewed first. Secondly, synergistic discussed. Then, intermediates explored important toxicity assessment methods proposed. Finally, potential future challenges This review provides an reference optimization future. Graphical
