Summary: This study presented a comprehensive identification of radicals in four typical UV-based homogeneous AOPs using in-situ EPR analysis. The radical formation mechanism was clarified based on the EPR results. A reliable EPR method was proposed to identify alkoxy and alkyl radicals in the UV/PAA system, and the addition of specific organic solvents effectively identified oxygen-center and carbon-center radicals.

Summary: Sustainable improvement is related to key variables that contribute to stable and secure positions. Hazardous substances and unsuitable soils have become one of the most important issues of insecurity for masculinity. Various countries have been monitoring unsafe substances and hazardous products. Although the safe evacuation of hazardous wastes has been an ongoing issue, research on the contrasting effects of dangerously bad backgrounds on anthropological well-being and conditions has determined that the unsafe overflow group will continue to be addressed during the current highest protection programs.

Summary: The increase in pollutants released into water resources, such as hazardous refractory contaminations, organic dyes, pharmaceutical and pesticide contaminants, due to population growth and global industrialization, has become a major health issue worldwide. Magnetic MXene nanocomposites, which possess unique properties, easy production, low-cost preparation, and excellent pollutant degradation abilities, show great promise for various applications including biosensors, cancer theragnostic, imaging strategies, and particularly water treatment. This paper provides a review of the use of magnetic-MXene nanocomposites for removing contaminants from aqueous environments, discussing the concept of magnetic nanomaterials in water treatment, MXene applications and implications for water and wastewater pollutant degradation, and the role of magnetic-MXene nanocomposites in water treatment. Future trends in MXene and magnetic-MXene nanomaterials for water treatment and environmental applications are also discussed.

Summary: This study evaluated the effects of various quenchers on the mechanism of a cobalt mediated peroxymonosulfate (Co(II)/PMS) process and found that these quenchers not only quench target reactive species but also cause interference effects. Therefore, caution should be exercised when applying the quenching method to investigate the mechanism of the persulfate-based process.

Summary: The paper highlights the seriousness of antibiotic contamination and emphasizes the need for research on effective methods to remove antibiotics from water. It provides an overview of antibiotic concentrations in different types of water and explores various methods for elimination. The paper also compares the advantages and disadvantages of these methods and presents the removal percentages achieved in representative studies. Biological methods and membrane technology show the best elimination efficiency, while chemical methods and constructed wetlands perform poorly in removing antibiotics.

Summary: Dye-contaminated water poses a global problem due to its negative impact on human health and the aquatic environment. Photocatalysis using TiO2 as the prime choice catalyst shows promise for dye pollution remediation, but its low quantum efficiency under solar radiation limits commercialization. Research has focused on increasing TiO2's efficiency through doping and morphological modifications to enhance dye degradation under UV-Vis irradiation.

Summary: Microplastic pollution was systematically investigated in the Yangtze River Basin of China, including water, sediments, and soils. The abundance of microplastics showed a generally increasing trend from upstream to downstream, influenced by geographical and anthropogenic factors. Microplastics in sediments exhibited more prominent vertical migration than those in soils, with density and size playing key roles. The abundance and distribution of microplastics were significantly different among different compartments and correlated with geographical distance.

Summary: The carbon-catalyzed persulfate-based advanced oxidation process (PS-AOP) has gained attention for its green and economical nature. Sulfur-doped ordered mesoporous carbons (S-OMCs) were used to activate peroxydisulfate (PDS) for ciprofloxacin (CIP) removal. The study found a correlation between defect level and O-1(2) yield, and investigated the impact of various reaction conditions and water matrix. The S-OMC-1000/PDS activation system showed promising results for CIP removal, even in the presence of common inorganic anions and natural organic matter (NOM).
