Feb 15, 2021 · SR-AOPs are vastly studied in landfill leachate and petrochemical IWW effluents. Its advantages include the simultaneous HO /SO 4 − generation with non-radical pathways. Limitations include the difficulty to apply heating, microwave and ultrasound activation.

Nov 15, 2011 · To our knowledge, this study represented the first scientific effort to apply persulfate for leachate treatment. Our results demonstrated that SR-based AOP could adequately and simultaneously remove refractory organics and ammonia from landfill leachate.

Sulfate-radical-based advanced oxidation processes (SR-AOPs) have been successfully used in wastewater treatment, such as that containing antibiotics, pesticides, and persistent organic pollutants, for refractory contaminant degradation.

Sep 15, 2024 · Sulfate radical-based advanced oxidation processes (SR-AOPs) show great promise in water purification due to their strong oxidizing properties and high selectivity. The future development of SR-AOPs relies heavily on the advancement of catalysts.

High oxidation potential as well as other advantages over other tertiary wastewater treatments have led in recent years to a focus on the development of advanced oxidation processes based on sulfate radicals (SR-AOPs).

Jan 22, 2024 · The primary radicals in SR-AOPs, SO 4 •−, result from the activation of oxidants (PS/PMS). Therefore, the PS/PMS activation for improving the degradation of organic contaminants, including pesticides, depends significantly on the oxidant concentration.

Nov 27, 2020 · Sulfate-radical-based advanced oxidation processes (SR-AOPs) have been successfully used in wastewater treatment, such as that containing antibiotics, pesticides, and persistent organic pollutants, for refractory contaminant degradation.

The main challenges and mitigation strategies pertinent to the SR-AOPs are identified, which include (1) possible formation of oxyanions and disinfection byproducts, and (2) dealing with sulfate produced and residual PMS. Potential future applications and research direction of SR-AOPs are proposed.

Apr 1, 2022 · Integration of membrane filtration (MF) and sulfate radical-advanced oxidation processes (SR-AOPs) has progressively attracted extensive attention for environmental remediation because of simultaneous degradation and filtration of pollutants in wastewater.

Apr 15, 2022 · Compared with hydroxyl radicals(·OH)-based methods, SR-AOPs have a series of advantages, such as long half-life and wide pH range, the oxidation capacity of SO 4 •-approaches or even exceeds that of ·OH under suitable conditions. In this review, we present the progress of activating PS/PMS to remove TrOCs by different methods.
