Summary: In this study, zero valent iron (ZVI) derived from Fe-based prussian blue analogues was successfully synthesized and exhibited excellent charge transfer properties. The ZVI-2 catalyst effectively activated peroxymonosulfate (PMS), leading to rapid degradation of phenol with a removal efficiency of 94.9% within 24 minutes. The ZVI-2/PMS oxidation system showed good stability and strong anti-interference capability, making it a promising candidate for wastewater treatment.

Summary: The study investigated the removal mechanisms of sulfidated nanoscale zero-valent iron (S-nZVI) towards EDTA-chelated CdII (CdII-EDTA) and the effects of critical factors on CdII-EDTA removal by S-nZVI. Results showed that S-nZVI had a high removal capacity for CdII-EDTA and the mechanism involved two-step replacement reactions.

Summary: The study demonstrates that sulfide-modified nanoscale zero-valent iron (S-nZVI) is a more promising catalyst for activating persulfate (PS) compared to normal nZVI, especially in the treatment of saline pharmaceutical wastewater. The sulfidation behavior enhances the removal efficiency of chloramphenicol (CAP) and possible degradation pathways of CAP in the S-nZVI/PS system were inferred through liquid chromatography-mass spectrometry (LC-MS) and density functional theory (DFT) calculations.

Summary: The study compared the degradation of iprodione (IPR) by UV-C light, zero-valent iron (ZVI), and zero-valent aluminum (ZVA) activated persulfate (PS) oxidation processes in distilled water (DW) and simulated urban wastewater (SWW). The results showed that ZVI/PS treatment was the most effective oxidation process in SWW, with the treatment performance being strongly influenced by the constituents of SWW, and UV-C/PS treatment being the most sensitive to it.

Summary: This study demonstrates the enhancement of peroxide activation efficiency and organic contaminant degradation by mechanically silicified microscale zero-valent iron (mZVI). The silicification process improves the generation of reactive intermediates, resulting in a significant increase in sulfamethazine removal rate. Continuous generation of ferrous ions in the Si-mZVI(bm)/PDS system after silicification contributes to the excellent performance of peroxide activation.

Summary: This study investigates the use of zero-valent iron activated peroxidized sulphate (ZVI/PDS) synergistic action for the effective removal of EDTA-chelated copper. The results show that the ZVI/PDS process significantly improves the removal efficiency of complexed copper and total organic carbon compared to ZVI alone. Factors such as the molar ratio, initial pH, ZVI dosage, and PDS dosage influence the removal efficiency of complexed copper. Analysis indicates that the method can reduce chelated copper and immobilize it on the ZVI surface.

Summary: In this study, the combination of ascorbic acid with zero-valent iron and peroxymonosulfate was found to enhance the degradation of benzoic acid. The removal efficiency of benzoic acid was significantly improved compared to the conventional system. Ascorbic acid played a key role in promoting the generation of reactive oxygen species, leading to enhanced degradation performance.

Summary: The study demonstrated that the nZVI/BC activated PS system could achieve over 90% removal of three NCB isomers at a low initial concentration. The combination of nZVI/BC composite and PS showed superior performance to using PS alone, with optimal treatment conditions being a Fe:BC ratio of 1:1, Fe amount of 6 mmol/L, and a mole ratio of Fe to persulfate of 1:1.

Summary: This study developed a sample called FA-ZVIbm by ball-milling zero-valent iron (ZVI) with formic acid (FA), which showed remarkable performance in removing heavy metal complexes, specifically Cu(II)-ethylenediaminetetraacetic acid (Cu(II)-EDTA). The addition of FA greatly enhanced the removal efficiency, increasing the removal rate constant by 80 times. The improvement was attributed to the formation of a ferrous formate (Fe (HCOO)2) shell on the surface of FA-ZVIbm, which facilitated the activation of reactive oxygen species (ROS) and the leaching of Fe3+.

Summary: Short-term exposure to PM2.5 and CO is associated with increased non-accidental and respiratory mortality, while PM10 is related to hypertension-related deaths. Urban and rural residents should avoid polluted air, especially during dust storms to reduce health risks. More serious air pollution control is needed in Ahvaz.

Summary: This study investigated the characteristics, sources, and health risks of PM10-bound polycyclic aromatic hydrocarbons (PAHs) on residents in different regions of Ahvaz, Southwest Iran. The results showed that industrial areas had the highest PAHs levels, while residential areas had the lowest. Industrial processing and petroleum refining were identified as major outdoor sources of PAHs. Increased exposure concentration of PAHs was found to significantly increase the risk of health issues.
