Summary: In this study, rGO, Co3O4, and rGO-Co3O4 composites were successfully synthesized and evaluated for their catalytic activity in degrading TC in aqueous solutions. The rGO-Co3O4 composite exhibited significantly enhanced efficiency compared to pure Co3O4, showing potential as a recyclable catalyst system. The degradation process primarily followed pseudo-first order kinetics and was influenced by various factors such as pH, TC concentration, catalyst dosage, and PS concentration. HO dot and SO4 dot- radicals generated from the rGO-Co3O4/PS system were key species in degrading TC in solutions.

Summary: This study reports the presence of six new aromatic nitrogenous disinfection byproducts (DBPs) in drinking water. Haloanilines completely degrade in the presence of chlorine within 1 hour, but about 20% remains in the presence of chloramine after 120 hours. Haloanilines show high stability in the absence of disinfectants at pH 5-9. Eight haloanilines were detected in chloraminated finished water and tap water, with the highest total concentration reaching 443 ng/L. The cytotoxicity of haloanilines was lower than that of regulated DBPs. The formation and control of haloanilines in drinking water call for further investigation.

Summary: Snow with large specific surface area and strong adsorption capacity can effectively adsorb atmospheric pollutants, leading to an increase in disinfection by-product (DBP) precursors in surface water. The dissolved organic matter (DOM) in meltwater is mainly composed of low molecular weight organics with low aromaticity and high unsaturation. DBP formation and cytotoxicity indexes in chlorinated meltwater are positively correlated with air quality index and are influenced by snowfall stages. The yield of halonitromethanes in meltwater is significantly higher than that in surface water.

Summary: In this study, it was discovered that the level of TOX in chlorinated waters had been significantly underestimated under common analytical conditions. The addition of quenching agent sodium thiosulfate resulted in a two-phase decomposition pattern of total organic chlorine and total organic bromine, indicating the important toxicological significance of the DBPs responsible for TOX decomposition. Nontarget analysis using high-resolution mass spectrometry revealed the molecular formulas for the decomposed TOX, and it was found that the level of unknown TOX in chlorinated waters was considerably higher than previously thought.

Summary: This article provides a comprehensive overview of the distribution, biological traits, risks, and control methods of Limnoperna fortunei. The planktonic larval stage is identified as a critical period for the expansion of this species, and its biofouling process relies on the adhesion of byssus to substrates. Various physical and chemical methods have been proposed and used to control Limnoperna fortunei, with sodium hypochlorite showing effectiveness in preventing adhesion. However, effective and environmental-friendly antifouling strategies are still lacking, particularly in drinking water treatment systems. This review not only enhances the understanding of Limnoperna fortunei but also provides guidance for prevention and control.

Summary: This study investigated the occurrence of CX3R-type disinfection byproducts in finished water of seven drinking water treatment plants sourced from Lake Tai with high levels of dissolved organic nitrogen. Results showed higher concentrations of nitrogenous DBPs in comparison to other areas in China, likely due to elevated DON levels and serious eutrophication of the source water. Advanced treatment processes were found to be effective in removing CX3R-type DBP precursors, with dibromoacetonitrile (DBAN) identified as the most important species in finished water. Additionally, a predictive model for DBAN concentration revealed the essential roles of DON and bromide in its formation.

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.
