“…Electrolytic activation of persulfate has been successfully applied in the treatment of complex wastewater matrices, such as dyeing wastewater [ 24 ], industrial effluent containing dinitrotoluenes [ 25 ], washing machine effluent [ 26 ], oil sands process water [ 8 ], and cyanide-containing wastewater [ 27 ]. The conditions used in the experiments and the main results obtained are summarized in Table 1 .…”

“…In a different study, utilizing an organic wastewater with high concentration in cyanide (CNW), Yang and collaborators [ 27 ] also evaluated the influence of applied current, temperature, and initial pH in the single electrolytic activation of PDS, and compared the results with electrooxidation (EO) and PDS oxidation stand-alone. After 24 h assays, the COD removals were: PDS (0.1 M)—36.9%, EO (20 mA cm −2 )—82.3 %, EO + PDS (20 mA cm −2 , 0.1 M)—99.5%.…”

“…If anode materials, such as BDD, are utilized, COD and TOC removal increase with applied current density due to direct and indirect oxidation of the pollutants. However, degradation rate is gradually reduced during the assay, due to mass transport limitations when the organic load became lower [ 27 ].…”

“…Moreover, oxygen solubility decreases with temperature, leading to lower electrogenerated H 2 O 2 , which points to a degradation mechanism mainly ascribed to the sulfate radical as temperature increases [ 25 ]. However, for high increases in temperature, only small increases in organic load removal may happen, probably because higher temperatures promote radicals quenching reactions [ 27 ].…”

“…In the presence of carbonates, organic degradation rate is also favored at acid conditions, since carbonate and bicarbonate concentration decrease, thus contributing less to the inhibition of persulfate and hydroxyl radicals. Energy consumption also increases with pH [ 27 ].…”

Complex wastewater matrices present a major environmental concern. Besides the biodegradable organics, they may contain a great variety of toxic chemicals, heavy metals, and other xenobiotics. The electrochemically activated persulfate process, an efficient way to generate sulfate radicals, has been widely applied to the degradation of such complex effluents with very good results. This review presents the fundamentals of the electro-persulfate processes, highlighting the advantages and limitations, followed by an exhaustive evaluation on the application of this process for the treatment of complex industrial effluents. An overview of the main relevant experimental parameters/details and their influence on the organic load removal is presented and discussed, having in mind the application of these technologies at an industrial scale. Finally, the future perspectives for the application of the electro-persulfate processes in the treatment of complex wastewater matrices is outlined.
