Summary: Using calcium sulfite as a slow-release source of sulfur dioxide, the effective working pH range of permanganate activation by sodium sulfite was extended from <= 7.0 to <= 9.0. The presence of calcium ions in the system led to enhanced precipitation of manganese dioxide, resulting in very low residual manganese levels. The Mn(VII)/CaSO3 system demonstrated a unique two-stage oxidation process with improved understanding of reaction kinetics and reactive oxidants.

Summary: The Fe3+-EF/sulfite process enhances the degradation and mineralization of organic pollutants by preventing Fe3+ precipitation and accelerating the iron cycle, resulting in improved H2O2 utilization efficiency and reduced electric energy consumption. Reactive species like SO3 center dot-, SO4 center dot-, center dot OH, O-2(center dot-) and O-1(2) were identified as responsible for the degradation of pollutants in the process. The process also broadens the pH application range and shows great potential for cost-effective removal of refractory organic pollutants.

Summary: Efficient removal of organic contaminants is challenging in complex environmental matrices, especially under high salinity conditions. This study proposes the use of FePc/CN-PMS process as a selective and efficient method for organic contaminant elimination. The FePc/CN-PMS process generates high-valent iron-oxo species (FeIVO2+) as the dominant active species, leading to effective degradation of organic compounds. The 5%FePc/CN-PMS system demonstrates resistance to inorganic anions and dissolved organic matter, making it suitable for practical water remediation.

Summary: This study found that pollutants containing phenolic moiety can greatly enhance the efficiency of the Fe(III)/H2O2 system without catalyst in degrading pollutants. Kinetics analysis revealed the self-catalytic degradation of the pollutants, with the best performance observed at pH 4.0. Spectroscopic measurements and theoretical calculations revealed a previously overlooked self-catalytic mechanism involving the formation of a yellow-colored high-spin P-Fe(III)-OOH complex, which subsequently converts to Fe(II). The oxidation of phenolic moiety generates hydroquinone, which also facilitates the cycling of Fe(III)/Fe(II) and the generation of hydroxyl radicals responsible for efficient decontamination.

Summary: The increasing use of plastic products in agriculture has led to the accumulation of microplastics and nanoplastics in agricultural soils, which raises concerns about their impact on soil health, crop productivity, and food safety. The interaction between plants, soil, and microplastics/nanoplastics can negatively affect plant growth and induce oxidative stress. However, the current knowledge about the fate and impact of microplastics/nanoplastics in the plant-soil nexus is limited, hindering further progress in this field. This review aims to address this gap by summarizing the sources, investigation techniques, impact on soil properties, accumulation in plants, and possible phytotoxicity mechanisms of microplastics/nanoplastics in agriculture.

Summary: This study investigated the kinetics and mechanisms of the reactions between Feaq II and PMS or PDS at different pH values, as well as the influence of bicarbonate (HCO3-). The results showed that FeaqIV was the dominant oxidizing species in the absence of HCO3-. In the presence of environmentally relevant concentrations of HCO3-, carbonate radical anion (CO3 center dot-) became the dominant reactive species. These findings provide insights for advancing persulfate-based advanced oxidation processes (AOPs) in oxidizing pollutants in natural water.

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.
