Summary: Extensive studies have been conducted on phosphate removal by micron-scale zero-valent iron (mZVI). The mechanisms of phosphate removal were elucidated using ATR-FTIR, XRD, and XANES techniques, revealing that precipitation is the main pathway for phosphate removal by ZVI under aerobic conditions. This study significantly improves our understanding of the fundamental processes involved in phosphate removal by ZVI.

Summary: The study found that Langmuir isotherm and pseudo 2nd order kinetic model were the best models to describe the removal of phosphorus by nanoscale zero-valent iron (NZVI). The research also confirmed the applicability of the proposed models in interpreting the experimental data and revealed the involvement of chemisorption mechanism in the removal process. Additionally, thermodynamic analysis showed the endothermic nature in the NZVI/P system and the occurrence of sorption and reaction rate analysis on two main diffusion steps.

Summary: In this study, a nanocellulose-based composite, NC-nZVI, was developed for efficient removal of nickel. The nZVI was anchored to nanocellulose through a liquid-phase reduction method, resulting in varied morphology and dispersion status. Among the developed composites, CNC-nZVI showed the most evenly distributed nZVI particles. The binding between NC and nZVI was achieved through hydrogen bonds, electrostatic attractions, coordination-covalent bonds, and steric hindrance. The CNC-nZVI composite exhibited significantly higher removal efficiency of Ni2+ compared to bare nZVI, and remained effective under a wide pH range and in the presence of interference ions like NO3-, Cl-, and Ca2+. The observed hollow-out structure and Tafel extrapolation curves indicated that CNC activated diffusion path and accelerated electronic transfer from nZVI. The superior removal performance of NC-nZVI and the abundance of raw materials make it a promising material for environmental remediation and wastewater treatment.

Summary: Remediation of Cr(VI) pollution by nanoscale zero-valent iron-loaded biochar (nZVI-BC) is a hot research topic. The interaction between natural organic matter (NOM) and Cr(VI) on their adsorption on nZVI-BC was investigated. nZVI-BCs with different ratios of Fe:C were prepared, and the optimal Fe:C ratio was determined to be 3:1. Adsorption experiments showed a strong competitive adsorption between Cr(VI) and NOM. Characterization techniques revealed the mechanisms behind the decreased Cr(VI) reduction and adsorption, as well as the decreased adsorption of NOM.

Summary: The study demonstrates that nZVI can effectively remove U(VI) from strongly alkaline solutions in anaerobic conditions, with a reduction efficiency of up to 95.5%, but the efficiency drops significantly in aerobic conditions due to oxidation and desorption processes. This offers new insights into the mechanisms of U(VI) interactions with nZVI in alkaline media and provides a potential approach for uranium recovery from spent nZVI.

Summary: This study investigated the influence of aged nanoscale zero-valent iron (A-nZVI) amendment and capping on the mobilization of phosphorus from sediment to overlying water. The results showed that high A-nZVI dosage effectively reduced the release of dissolved reactive phosphorus (DRP) from sediment to overlying water under oxygen deficit conditions. Low A-nZVI dosage also had the ability to diminish the risk of DRP released from sediment into overlying water. A-nZVI capping further hindered DRP release and had higher controlling efficiency than A-nZVI amendment under oxygen deficit conditions.

Summary: Promoting residential water conservation is crucial in addressing water shortages caused by increasing water demand. A questionnaire survey of 514 Japanese adults was conducted to measure how various social, psychological, and behavioral variables influence individual water use and conservation behavior. The study found that families are more likely to adopt water conservation practices and use less water if they have positive attitude, greater awareness and responsibility about water issues, stronger emotions, habits and involvement in water-saving initiatives or campaigns. The suggested model explained 55% and 57% of the variation in water consumption and conservation behavior.

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.
