Summary: Effective adsorption of radioactive iodine (I2) contaminants is important for environmental protection. This study focused on high adsorption rate rather than just high adsorption capacity. Two novel cationic covalent triazine frameworks (CCTFs) with abundant pyridine cation sites were successfully prepared under high-temperature polymerization conditions. These CCTFs exhibited ultra-high stability, high surface area, and a large electrostatic potential gradient. The synthesized CCTFs showed super-fast I2 vapor adsorption rates and could remove 99.9% of I2 contaminant in a high-concentration I2/hexane solution within 0.5 min.

Summary: In this research, benzimidazole and -CH3 groups were successfully integrated into UiO-66 through a step-by-step linker modification strategy to form Bim-UiO-66 and Bim-UiO-66-Me. Both benzimidazole derivatives showed better performance than UiO-66 in the removal of heavy metal oxo-anions, with Bim-UiO-66-Me exhibiting the highest performance, with sorption rates and capacities 7.5 and 3.0 times higher than UiO-66, respectively. This study not only provides a promising candidate for removal of heavy metal oxo-anions in wastewater treatment but also presents a new strategy for the design of high-performance adsorbents.

Summary: This study used suspect and nontarget screening techniques to identify organo-phosphate triesters and diesters (tri-OPEs and di-OPEs) in influent and effluent samples from 25 municipal wastewater treatment plants (WWTPs) in China. A total of 33 different OPE molecules were identified, with 11 being detected in wastewater for the first time and 4 being new to the public. Di-OPEs accounted for a significant portion (53% on average) of the total OPEs in all tested samples. Most of the OPEs could not be eliminated after treatment in these WWTPs, and some di-OPEs even accumulated. The ecological risk analysis of OPEs in the effluent highlighted the previously unrecognized exposure risk of emerging OPEs for aquatic living organisms. These findings provide a comprehensive understanding of the environmental relevance of OPEs in WWTPs on a country scale and can guide the upgrade of treatment protocols and governmental regulations in the future.

Summary: Immobilization of enzymes within metal-organic frameworks can enhance their long-term usability, but it often leads to a trade-off between stability and activity. This study shows that the trade-off can be solved by controlling defects through competitive coordination.

Summary: The application of heterogeneous advanced oxidation processes (AOPs) in wastewater treatment is hindered by low oxidant utilization efficiency, slow catalytic cycling, and matrix interference. This study demonstrates that amorphous zirconium dioxide (aZrO2), a redox-inert metal oxide, can efficiently activate peroxymonosulfate (PMS) to degrade organic micropollutants even under low oxidant doses and complex matrices. The surface Zr(IV)-PMS* complex is identified as the principal reactive species, and the interaction between Zr atom and PMS leads to prolonged O-O bond and elevated oxidation potential for direct reaction with contaminants.

Summary: In this study, a novel octahedral carbon -encapsulated zirconium oxide catalyst (ZrO2-C) was developed with large specific surface area, highly-dispersed sub-5 nm active sites, and strong metal-support interactions. The catalyst exhibited excellent performance for peroxymonosulfate activation, and a two-step catalytic mechanism was proposed. The study also demonstrated the high selectivity of the catalytic process towards electron-rich compounds, with only those organics with EHOMO values higher than ca.-6.52 eV being oxidized. Overall, this research provides mechanistic insights into the catalytic selectivity of Zr-based catalysts and advances their further application in Fenton-like systems.

Summary: Dual-atom catalysts (DACs) show great potential in various catalytic reactions, but the origin of their high activity and the mechanism behind the enhancement are still not well understood. In this study, FeCo-N/C dual-atom catalyst was compared with its single-atom counterparts in activating peroxymonosulfate (PMS) for pollutant abatement. It was found that the spin-state reconstruction on FeCo-N/C effectively improves the electronic structure of Fe and Co, leading to enhanced PMS activation efficiency and a remarkable boost in the Fenton-like reaction. The study provides a mechanistic understanding of the enhanced catalytic activity of DACs and expands their potential applications.

Summary: The surface properties and microstructure of graphene oxide (GO) membranes can be regulated to enhance nanofiltration performance. The surface hydrophilicity and zeta potential of GO membranes can be adjusted by alkaline treatment time, and the presence of tiny defects in GO sheets can increase the number of pores and decrease the length of water nanochannels. These adjustments enable GO membranes to exhibit fast and selective water permeation, demonstrating excellent nanofiltration performance.

Summary: The Fe(III)/H2O2 system showed high efficiency in remediation of tetracycline (TC) in water, even faster than the Fe(II)/H2O2 system. TC also initiated the degradation of other refractory pollutants. Complexation between Fe(III) and TC was observed with a stoichiometric ratio of 1:1 and electron transfer from TC to Fe(III) resulted in the production of Fe(II), which served as the initiator of the Fenton reaction. The main reactive species was found to be .center dot OH, facilitating the hydroxylation of TC and the reductive transformation of Fe(III) to Fe(II).

Summary: This study investigated the occurrences and fates of 27 legacy and emerging PFASs in textile dyeing wastewater treatment plants. It was found that most conventional processes were inefficient in removing PFASs, especially legacy PFASs. Microbial processes could remove emerging PFASs to some extent but commonly elevated legacy PFAS concentrations. Reverse osmosis (RO) could remove over 90% of PFASs and enrich them into the RO concentrate.

Summary: In this study, the evolving role of calcium ion (Ca2+) on phosphate removal by nanosized hydrated lanthanum oxides confined in cross-linked polystyrene beads was investigated. The presence of Ca2+ initially enhances the phosphate uptake by the adsorbent, but with ongoing cyclic runs, the role of Ca2+ becomes negative. The formed Ca-P precipitates accumulate on the surface of the nanoparticles and deplete the active adsorptive sites, leading to the formation of irreversible LaPO4 center dot xH(2)O under nanoconfinement.
