Summary: Nanobubble and ultrasonic cavitation were used to enhance oxidation reactions of ozonation, with nanobubbles increasing ozone dissolution by a factor of 16 and ultrasonic cavitation generating hydrogen peroxide. The process achieved significant improvements in both the loss of emitted ozone and radical recombination, demonstrated by the decomposition of rhodamine B. The combination of nanobubble and ultrasonic cavitation sustained oxidizing power by continuous dissolution of ozone and successive radical generation.

Summary: This study assessed and compared the efficiencies of ozonation and ozone with hydrogen peroxide for the removal of organic micropollutants (OMPs), as well as the inactivation of bacteria and viruses, and the formation of bromate and biodegradable organics in municipal wastewater effluent. The results showed that ozonation effectively eliminated 39 OMPs, with 22 OMPs achieving a removal rate of 54 ± 14% at an ozone dosage of 0.5 gO(3)/gDOC. The concentration and exposure time of ozone were positively correlated with microbial inactivation levels, and O-3/H2O2 minimized bromate formation but decreased bacteria/virus inactivation. Ozonation also produced biodegradable organics, which could be removed through post-biodegradation treatment.

Summary: The formation of oxygen in caffeine aqueous solutions happens through self-decomposition reactions of hydrogen peroxide, used as an oxidant in photo-Fenton treatment. Oxygen is not released at concentrations lower than a specific value. As the concentration of catalyst increases, the rate of oxygen generation increases until reaching a peak and then starts to decrease.

Summary: In this study, a hydrogen peroxide-free resin photo-Fenton system was developed for efficient degradation of organic pollutants. The system exhibited excellent performance due to the synergistic effect of hydroxyl radicals and holes, resulting in significantly higher degradation rates compared to other systems. The high performance was mainly attributed to the reduction of iron ions by electrons and increased utilization of hydrogen peroxide, as well as the prevention of macromolecular polymer intermediates, leading to high mineralization efficiency. This finding offers a promising route for eco-friendly and efficient wastewater treatment using visible-light photo-self-Fenton systems.

Summary: A simple one-step thermal oxidation process was established to increase {110} and {111} nanofacets on ceria nanocubes, leading to improved enzymatic activities. The enhancement may be attributed to the sawtoothlike {111} nanofacets and defects that facilitate oxygen mobility and the formation of oxygen vacancies on the surface, without changing the bulk properties. Additionally, possible mechanisms of nanoceria as artificial enzymes were proposed in this study, suggesting the potential for future design of highly efficient nanozymes.

Summary: This study evaluated the photocatalytic degradation of the antibiotic cefuroxime (CFX) using heterogeneous photo-Fenton with alpha-Fe2O3-TiO2 as a catalyst under simulated solar radiation.

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.
