Summary: This study reported a novel pathway for the generation of sulfate radical (SO4 center dot-) during the oxidation of neonicotinoids by peroxydisulfate (PDS) without any additional chemicals. Thiamethoxam (TMX) was found to activate PDS via TMX anion radical (TMX center dot-), leading to the generation of SO4 center dot-. This pathway was also applicable to other neonicotinoids.

Summary: This study discovers that 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) can serve as both an activator and an electron shuttle to enhance the activation of peroxydisulfate (PDS) and enhance the degradation of diclofenac (DCF). The PDS/ABTS system generates multiple reactive species, with ABTS(center dot+) and (OH)-O-center dot directly contributing to the degradation of DCF. The PDS/ABTS system shows good anti-interference capacity and further improved performance can be achieved by encapsulating ABTS into cellulose.

Summary: This study demonstrates the effective removal of diclofenac (DCF) using the Cu(II)/hydroxylamine (HAm)/peroxydisulfate (PDS) system under neutral conditions. The introduction of HAm significantly enhances the degradation of DCF by accelerating the Cu(I)/Cu(II) cycle. The study also investigates the effects of various operational parameters and water matrix components on DCF degradation. Additionally, the Cu(II)/HAm/PDS system shows potential for degrading other emerging organic contaminants.

Summary: This study examined the effects of bromide (Br-) at fresh water levels on radical chemistry in the UV/peroxydisulfate (UV/PDS) process. The presence of Br- promoted the conversion from sulfate radical (SO4-) to hydroxyl radical (HO-) and secondary reactive bromine species (RBS), significantly altering the radical chemistry of the process. Co-existing Cl- further enhanced the conversion from SO4- to HO- when combined with Br-.

Summary: Electrokinetic transport coupled with electrical resistance heating activation of peroxydisulfate is a novel method for in situ soil remediation. A lab-scale simulation device was constructed to monitor the transport and transfer of peroxydisulfate, target pollutants, and process parameters, and to evaluate the physicochemical properties and bacterial community of treated soil. The results showed that adding 10 wt% peroxydisulfate to both the anode and cathode optimized the transfer rate and cumulative concentration of peroxydisulfate under electrokinetics. After alternating electrokinetic transport and electrical resistance heating activation of peroxydisulfate for two cycles, the phenanthrene degradation efficiency reached high levels in evenly distributed wells between electrodes.

Summary: This study found that pre-oxidation of iron-rich sludge with heat-activated peroxydisulfate (PDS) can enhance the production of volatile fatty acids (VFAs) and the release of iron-bound phosphorus (Fe-P), thereby increasing the concentration of recoverable phosphorus. PDS oxidation effectively disintegrated the sludge and generated sulfate simultaneously. The disintegration of sludge promoted the hydrolysis of organic matter, leading to increased VFAs yield, while the sulfate was reduced to sulfide during anaerobic fermentation (AF) and precipitated with iron to release Fe-P.

Summary: In this study, multi-walled carbon nanotubes (MWCNT) were utilized to activate peroxydisulfate (PDS) for the degradation of 2,4-dichlorophenol (2,4-DCP), and the effects of solution pH, PDS concentration, 2,4-DCP concentration, and MWCNT loading on the degradation process were investigated. The results indicated that surface reactions involving both surface-bound radicals and direct electron transfer were responsible for 2,4-DCP degradation, with the rate increasing with higher solution pH, PDS concentration, and MWCNT loading. Reusability tests suggested that surface sites responsible for surface-bound radical formation were deactivated after PDS activation, while those responsible for direct electron transfer remained active.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
