Summary: The study investigated the electrochemical activation of peroxymonosulfate (PMS) at a carbon cloth anode for the degradation of sulfamethoxazole (SMX). It was found that higher PMS concentrations and current densities improved the degradation of SMX, with the presence of chloride ions enhancing degradation and humic acid inhibiting it. The degradation pathways were identified to include hydroxylation, cleavage of S-N bond, and oxidation of aniline group, with sulfate radical, hydroxyl radical, and singlet oxygen contributing to SMX degradation in the system.

Summary: Electrochemically activated peroxymonosulfate with mixed metal oxide electrodes (EA-PMS-MMO / MMO) is an effective method for the degradation of sulfadiazine. Both the anode and cathode of MMO play important roles in the activation of peroxymonosulfate. Reactive species such as HO·, SO4·-, O2·- and 1O2 are generated during the process, with 1O2 being the most abundant. The degradation pathways of sulfadiazine were proposed based on density functional theory. The overall toxicity of the compound and its degradation intermediates was significantly reduced after degradation by EA-PMS-MMO / MMO. This technology provides a reliable approach for the degradation of organic contaminants and holds great potential for application.

Summary: This study introduced sodium metaborate (NaBO2) into the thermal/PMS system to enhance the degradation of acetaminophen. NaBO2 showed better performance than sodium tetraborate in accelerating acetaminophen degradation at a wide pH range. The system produced 1O2 and HO· as the main ROS responsible for acetaminophen degradation. Three elimination pathways for acetaminophen were proposed based on the identified intermediates. NaBO2 dosage, PMS concentration, and reaction temperature were found to accelerate acetaminophen removal. Cl- and Br- promoted acetaminophen removal, while humic acid had an adverse effect. Additionally, NaBO2 significantly inhibited the production of chlorinated by-products in Cl--containing water treatment.

Summary: Graphene, a new class of nanomaterials, has great potential in environmental treatment. However, the use of graphene powder is limited by its shape. Therefore, it is significant to construct large-volume three-dimensional graphene structures for practical applications. This paper introduces commonly used methods for preparing three-dimensional structures, such as the template method and self-assembly method. However, these methods have disadvantages that can lead to structural defects and affect the mechanical properties of the fabricated structures. Additive manufacturing stands out with its advantages of easy operation, precise design, and batch preparation. The paper reviews the preparation methods based on graphene macroscopic bodies and their applications in environmental treatment, as well as discusses the difficulties and future development of three-dimensional graphene architectures for applications.

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.
