Abstract

Dye-bearing wastewater presents a substantial ecological risk. Consequently, there is a critical requirement for efficient treatment strategies. Electrochemical advanced oxidation processes (EAOPs) utilizing hydroxyl and sulfate radicals emerge as viable alternatives to degrade dye pollutants effectively. This review article emphasizes the implementation of EAOPs in the treatment of both synthetic and actual dye-bearing wastewater. The fundamentals, chemistry, and recent developments concerning hydroxyl radicals-based EAOP, including anodic oxidation, electro-Fenton, and sulfate radicals-based EAOP, have been thoroughly reviewed. Furthermore, the article explores the comparative effectiveness of the individual hydroxyl and sulfate radical systems as well as the integrated hydroxyl and sulfate radical systems within a singular electrochemical cell. It has been established that sulfate radicals demonstrate a higher oxidation potential, greater pH adaptability, and a longer half-life in comparison to hydroxyl radicals, making them efficient for dye degradation when assessed against anodic oxidation and electro-Fenton processes. Thus, EAOPs represent a promising technological approach for the remediation of dye-bearing wastewater.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
