Advances in the decontamination of wastewaters with synthetic organic dyes by electrochemical Fenton-based processes

Separation and Purification Technology, Journal Year: 2023, Volume and Issue: 316, P. 123764 - 123764

Published: April 5, 2023

Large amounts of diverse colored synthetic organic dyes are discharged from industrial effluents in the environment causing non-esthetic pollution and serious health-risk problems. Dyes very stable upon solar irradiation, temperature, biological treatment, then being non-removed conventional wastewater treatment plants. The decontamination dyeing by potent methods has received increasing attention over last years, showing a marked relevance electrochemical Fenton-based processes consisting H2O2 electro-generation its catalytic decomposition with Fe2+ to form ∙OH. This paper presents comprehensive review these period 2018–2022 dealing discoloration mineralization solutions real wastewaters single or mixed dyes. Homogeneous electro-Fenton (EF), heterogeneous EF solid catalysts functionalized cathodes, photoelectro-Fenton (PEF), microbial fuel cells, other hybrid adsorption, nanofiltration, electro-peroxone, photoelectrocatalysis, sequential electrocoagulation sonication summarized. principles explained understand role oxidizing agents generated. accumulation at pH 3.0 is described cathodes raw modified carbonaceous materials as well gas-diffusion electrodes, effect anode, electrolyte composition, applied current density cathodic potential, dye contents on homogeneous performance discussed. Rapid much slower were found EF. Similar behavior was obtained for EF, although allowed operating more neutral without sludge precipitation. removal improved PEF (SPEF) due positive photolysis Fe(III) species UVA light sunlight, respectively. SPEF can be envisaged best cost-effective destruction.

Significantly Enhanced Electrocatalytic Reduction of Chloramphenicol from Water Mediated by Fe–F–N Co-doped Carbon Materials

ACS ES&T Water, Journal Year: 2023, Volume and Issue: 3(5), P. 1385 - 1394

Published: April 14, 2023

Chloramphenicol (CAP) is a widely used antibiotic drug and poses great threat to human health the ecosystem. In this work, an iron–fluorine–nitrogen (Fe–F–N) co-doped porous carbon material was innovatively prepared applied for electrocatalytic reduction of CAP from water, excellent treatment performance achieved. For initial concentration 10 mg/L, after 60 min operation, almost 100% removed. The active Fe(II) sites F-doping-induced electronic structure Fe-FNC facilitated reductive degradation by promoting electron transfer, rather than H*-mediated indirect process. Therefore, better obtained compared other catalysts such as Fe-NC FNC. reaction pathways were elucidated, ecotoxicity products assessed. toxicity intermediate found be significantly reduced, indicative good prospect method CAP-containing wastewater pretreatment.
