“…Persulfate combined with UV has been proved to be a powerful oxidizing agent for the degradation of some organic contaminants due to high yield of sulfate radicals formation and its longer half-life compared to other reactive oxygen species 17 . The conversion of Acid Blue 129 could reach 87% at peroxydisulfate concentration of 2.5 mmol/L after 5 min and the research results illustrated that UV-activated peroxymonosulfate is more efficient for dye degradation than UV-activated peroxydisulfate 18 . UV activation could reduce the formation of by-products and hence could be more environmentally friendly.…”

Two low-pressure ultraviolet (UV) lamps at 185/254 nm with sodium persulfate in a pilot UV device were utilized for the degradation of reactive red (B-3BF) dye wastewater compared with two UV lamps at 185/185 nm and two UV lamps at 254/254 nm. The degradation performances of UV irradiation (254/185 nm) with sodium persulfate under different degradation times, flow rates, initial pH, initial Na2S2O8 concentrations and initial dye concentrations were investigated. The experimental results illustrated that the degradation percentage of B-3BF dye could reduce to 90.42% with the energy consumption of 85.1 kWh/kg and the residual dye concentration of 1.92 mg/L by UV irradiation (254/185 nm) with initial Na2S2O8 concentration of 1.5 mmol/L and initial dye concentration of 20 mg/L. In addition, degradation performance of B-3BF dye wastewater by UV irradiation (254/185 nm) with sodium persulfate was more effective than those of UV irradiation (254/254 nm) and UV irradiation (185/185 nm). Therefore UV irradiation (254/185 nm) with sodium persulfate was promising for the degradation of B-3BF dye wastewater.

“…Consequently, it is imperative to eliminate organic dye contaminants before discharging wastewater. In recent years, many researchers have focused their attention on highly efficient advanced oxidation processes (AOPs) that generate reactive oxygen species (ROS). , AOPs based on the activation of peroxymonosulfate (PMS) can produce a variety of reactive oxygen species, which can oxidize most persistent organic pollutants and cause their rapid degradation. , Its asymmetric structure, high redox potential, long lifetime, and broad pH adaptability are considered more advantageous. , Usually, certain supplementary conditions would help activate PMS, including heat treatment, ultrasound, ultraviolet irradiation, microwave irradiation, etc. However, these methods often necessitate substantial external energy input, which would be difficult to achieve in some applications.…”

Metal oxides can activate peroxymonosulfate (PMS) for the catalytic degradation of organic dyes. However, achieving high catalytic efficiency, structural stability, ease of recovery, and recyclability remains challenging for both research and practical applications. To address these requirements, a bimetallic oxide, CuMnO 2 , was synthesized using a simple hydrothermal approach and was encapsulated to create hydrogel beads, CS-Ca@PEI/CuMnO 2 . Subsequently, CS-Ca@PEI/CuMnO 2 was used to activate PMS and establish a solid−liquid heterogeneous oxidation system (CS-Ca@PEI/CuMnO 2 /PMS) for the degradation of Congo red (CR). The effects of various parameters such as different systems, catalyst dosages, initial pH values, PMS concentrations, temperatures, and anion types on the catalytic degradation properties of CS-Ca@PEI/CuMnO 2 for CR were systematically evaluated. The results indicated that CS-Ca@PEI/CuMnO 2 has exceptional degradation capacity, achieving 91.0% degradation of CR at pH 7. After three degradation cycles, the catalyst maintained an 86.9% degradation efficiency compared to its original performance, highlighting its robust structural stability. The presence of reactive radicals, specifically 1 O 2 and • O 2 − , were confirmed through quenching experiments, X-ray photoelectron spectroscopy (XPS), and electron paramagnetic resonance spectroscopy (EPR). Liquid chromatography-tandem mass spectrometry (LC-MS) revealed ten proposed intermediates in the catalytic degradation process. Due to its exceptional catalytic performance, structural durability, recyclability, and ease of retrieval, the catalyst shows great potential for effectively removing organic pollutants from industrial wastewater.

“…However, the aforementioned activation methods still have some limitations. For example, UV activation, electro‐activation, thermal activation, and ultrasound activation processes require a significant amount of external energy consumption (Jing et al, 2011; Ramakrishnan et al, 2023). Additionally, metal ions in the activation process often require an acidic reaction environment, which can result in secondary environmental pollution after the reaction (Ghanbari et al, 2020; Yang et al, 2021).…”

In recent years, the synergistic degradation of water pollutants through advanced oxidation technology has emerged as a prominent research area due to its integration of various advanced oxidation technologies. The combined utilization of peroxymonosulfate (PMS) activation technology and photocatalysis demonstrates mild and nontoxic characteristics, enabling the degradation of water pollutants across a wide pH range. Moreover, this approach reduces the efficiency of electron hole recombination, broadens the catalyst's light response range, facilitates electron transfer of PMS, and ultimately improves its photocatalytic performance. The paper reviews the current research status of photocatalytic technology and PMS activation technology, respectively, while highlighting the advancements achieved through the integration of photocatalytic synergetic PMS activation technology for water pollutant degradation. Furthermore, this review delves into the mechanisms involving both free radicals and non‐radicals in the reaction process, and presents a promising prospect for future development in water treatment technology.
