Summary: In this study, a two-stage Reduction and Oxidation Synergistic Platform (ROSP) was evaluated for the removal of halogenated organic pollutants (HOPs). The ROSP successfully removed over 99% of 60 mg/L 4-chlorophenol (4-CP) by integrating catalytic reductive dehalogenation with biological co-oxidation. The ROSP used hydrogen as the sole electron donor, eliminating the need for extra carbon dioxide release.

Summary: A bioelectrochemical process combining two membrane-less reactors equipped with graphite granules counter electrode was developed for perchloroethylene removal. The reductive reactor completely reduced PCE into VC and Eth, which were efficiently removed by the oxidative reactor. Different redox niches in each compartment allowed the co-existence of both reducing and oxidative reactions, enhancing the overall efficiency of PCE removal.

Summary: This study focuses on the development of a naked eye observable colorimetric technique for the detection of halogenated solvents and monoaromatic hydrocarbons. Two divanadium(V) compounds were found to show distinct and instant blue color change when added to various colorless solvents, presumably due to ligand-to-metal-charge-transfer and ligand-to-ligand-charge-transfer processes. The practical applicability of the sensors was tested by investigating the colorimetric response in organic solvent mixtures, as well as smartphone RGB color value based colorimetric sensing for on-site detection.

Summary: The extensive production and consumption of plastics has led to a significant amount of plastic waste and pollution. Polyvinyl chloride (PVC) waste, with its high chlorine content, is a major contributor to the plastic waste stream and can generate hazardous chlorinated organic pollutants if not properly treated. This review examines PVC synthesis, applications, and the challenges of managing PVC waste. Dechlorination is crucial for the chemical recycling of PVC waste and PVC-containing plastic waste. The review discusses dehydrochlorination and dechlorination mechanisms of PVC using thermal degradation and wet treatments, as well as recent advancements in chemical treatments and dechlorination principles. It provides a comprehensive analysis of chemical recycling technologies for PVC waste and PVC-containing plastic waste, aiming to transform them into chemicals, fuels, feedstock, and value-added polymers.

Summary: This study investigates the removal performance of NH4+-N in the presence of co-existing halogenated phenol using waste lithium-ion batteries (LIBs) material-derived catalysts activating peroxymonosulfate system (LIBs/PMS). The results show that TCP can degrade rapidly within 2 minutes, regardless of the presence of NH4+-N. Interestingly, NH4+-N removal is initiated by TCP and is strongly dependent on TCP dechlorination. Moreover, NH4+-N removal is thermally accelerated in the temperature range of 25 to 60 degrees C.

Summary: This study investigated the effect of polyethylene microplastics (PE-MPs) on the disinfection of Escherichia coli (E. coli) in different water conditions. It was found that PE-MPs tended to agglomerate and reduce the inactivation rate of E. coli. Factors such as pH, natural organic matter (NOM), and cation concentrations were identified as influencing factors on the disinfection efficiency. However, the presence of PE-MPs mitigated the impact of these complex chemistry factors on the bacteria.

Summary: Compared with traditional liquid-liquid extraction, solid-phase extraction agents are important for the recovery of indium metal due to their convenience, solvent-free nature, and high activity. In this study, P2O4 was chemically modified using UiO-66 to form a solid-phase extraction agent, P2O4-UiO-66-MOFs, which showed excellent adsorption capacity for In(III). The adsorption process followed pseudo first-order kinetics and the adsorption isotherms fitted the Langmuir model. The modified P2O4-UiO-66-MOFs showed high stability and retained over 99% of the adsorption capacity after multiple cycles of adsorption-desorption-regeneration.

Summary: The interaction between groundwater matrices and nanoscale zero-valent iron (NZVI) affects the mobility of NZVI. In this study, polyacrylic acid-stabilized NZVI and Mg(OH)2-coated NZVI were investigated as representative stabilizers for NZVI. The presence of divalent cations and humic acid induced aggregation and sedimentation of NZVI-PAA, while encountered groundwater electrolytes could not effectively provide electrostatic repulsion. However, sonication of the NZVI slurry with groundwater eliminated the sedimentation behavior. In comparison, the settling behavior of NZVI@Mg(OH)2 was hindered, and it exhibited higher mobility after adsorption sites of the sand surface were exhausted.

Summary: Coal to ethylene glycol (CTEG) technology has gained increasing attention in the past decades. The production of nitric acid (NA) as a by-product during the oxidative esterification reaction can cause equipment corrosion and increase nitrogen replenishment and wastewater treatment costs. This study demonstrates the use of non-metallic B doped activated carbon (B-AC) as a catalyst to reduce NA in the CTEG process. The structure and physicochemical properties of B-AC were examined, and its catalytic performance and stability were evaluated. Results show that B-AC exhibits higher activity compared to pure activated carbon (AC) and has potential as a catalyst for reducing NA wastewater.

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.
