Summary: This study investigated the degradation of oxytetracycline by heat-activated peroxydisulfate and peroxymonosulfate processes. Response surface methodology was used to evaluate the effect of process parameters on oxytetracycline removal efficiency, showing significant results for both processes. The predicted oxytetracycline removal efficiencies for the PDS and PMS processes were 89.7% and 84.0%, respectively, with the PDS process having higher kinetic constants at all pH values than the PMS process.

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 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: 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: By designing and synthesizing open-shell molecules, researchers have successfully controlled the assembly of these molecules into a strong antiferromagnetic network. The high paramagnetic-to-antiferromagnetic transition temperature of around 40 K and the high single-crystal electrical conductivity indicate the potential of this material in electronic and magnetic applications.

Summary: Many aspects of sulfate radical-advanced oxidation processes, particularly under alkaline medium, are widely debated. This review examines the possible mechanisms of activation of peroxydisulfate (PDS) and peroxymonosulfate (PMS) under alkaline conditions based on available literature. The formation of various products (SO52-, HO2-) is discussed, highlighting their complex interactions and potential roles in persulfate activation and radical scavenging. The activation of persulfates in alkaline conditions is highly pH-dependent due to the dissociation centers in both PMS and HO2-. There is a need for more detailed mechanistic studies to address inconsistencies in the current literature. Additionally, the relevance of sulfate radical-based oxidation of hydroxide ions and the importance of hydroxyl radicals differ in chloride-poor and chloride-rich environments.

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: Sulfate radical-based advanced oxidation processes (SR-AOPs) are being recognized as an effective alternative for removing persistent pollutants in water. Persulfates, such as peroxydisulfate (PDS) and peroxymonosulfate (PMS), are commonly used sulfate radical donors. UV-activated PDS and PMS can efficiently degrade anthraquinone dye (AB129) and inhibit the formation of by-products. This research demonstrates the reduced ecotoxicity of treated water after degradation, confirming the environmental friendliness of sulfate radical-based processes.

Summary: Plasmonic metal nanoparticles can enhance the efficiency of photodynamic therapy. The protein corona formed around the nanoparticles in contact with biological fluids greatly affects the therapy's efficiency. The study shows that pectin-coated gold nanoparticles can improve the efficacy of riboflavin-based PDT in HeLa cells under standard serum conditions, while preincubation with serum may have negative effects.
