Summary: Phthalic acid esters (PAEs), commonly used as plasticizers to improve the flexibility of materials, are widely distributed in soil and wastewater, raising public concerns due to their endocrine-disrupting effects. A ferrihydrite-H2O2-bisulfite ternary system was developed for efficient degradation of dimethyl phthalate (DMP) in this study. Hydroxyl radical (・OH) was identified as the dominant reactive species for DMP degradation. The study also showed that bisulfite-assisted heterogeneous Fenton-like reactions could be a potential in-situ soil remediation technology for efficient degradation of PAEs.

Summary: Human urine is a significant source of contamination from antibiotics in the environment. Therefore, it is crucial to develop effective treatment technologies for the degradation of urine antibiotics in order to facilitate large-scale human urine reuse. This study investigated the removal of antibiotics from synthetic human urine using the nickel converter slag-laterite (NCS-LA) heterogeneous Electro-Fenton (heterogeneous-EF) process. The results showed that with artificial aeration at a rate of 0.5 L/min, a degradation efficiency of 95.25% for norfloxacin (NOR) was achieved under specific conditions (catalyst dosage 60 g/L, initial pH 3, applied current 80 mA). The natural aeration mode was found to be unsuitable for a single chamber undivided reactor with graphite felt (GF) cathode and Ti/RuO2-IrO2 anode, resulting in only 9.49% NOR degradation efficiency. In cycling experiments, NCS-LA demonstrated excellent reusability and stability, with only a 5.01% decrease in NOR degradation efficiency after six cycles. The leaching concentrations of heavy metals (Fe, Ni, Co, and Cu) after each cycle were low (0.01-3.72 mg/L). This strategy holds promise for the recovery and reuse of urine.

Summary: Dielectric barrier discharge (DBD)-biochar sequential batch experimental technology was used to degrade atrazine (ATZ) in soil. DBD treatment increased the hydrophilicity, particle size, and instability of soil particles, leading to the exposure of residual ATZ. Biochar introduction compensated for the shortcomings of sole DBD treatment and enhanced ATZ removal efficiency. Proposed ATZ degradation mechanisms included various reactions, such as dealkylation, dechloro-hydroxylation, and alkylic-oxidation.

Summary: In this study, three kinds of cerium-based metal-organic frameworks (Ce-MOFs) were synthesized and their adsorption performance on fluoride was investigated. The Ce-MOFs showed good fit to the pseudo second order kinetic model and Langmuir isothermal model. The maximum saturated adsorption capacities of Ce-BTC, Ce-PMA, and Ce-BDC were 70.7, 159.6, and 139.5 mg g(-1), respectively. Ce-MOFs exhibited stable and excellent performance at pH = 3-9, and the presence of coexisting anions did not affect their defluoridation performance. The study also demonstrated the potential of Ce-MOFs as superior fluoride adsorbents in real water samples.

Summary: Commercial molybdenum carbide (Mo2C) and ferrous iron (Fe2+) were investigated as co-catalysts for the activation of H2O2 in the treatment of organic contaminants. The presence of Mo2C effectively decomposed H2O2 and accelerated the conversion of Fe3+/Fe2+ compared to traditional Fenton process. Mo2C/Fe2+/H2O2 exhibited a significantly higher catalytic reactivity than MoS2, and the degradation rate constant of Rhodamine B in Mo2C/Fe2+/H2O2 was three times higher than that in Fe2+/H2O2. XPS analysis showed that Mo(II) and Mo(IV) played major roles in Fe3+ reduction, and EPR analysis confirmed the involvement of .OH, O-2(-), and O-1(2) in Mo2C/Fe2+/H2O2. ECOSAR toxicity assessment revealed a decrease in the toxicity of RhB degradation products after treatment. Overall, this study presents a promising Mo2C co-catalyzed Fenton process for efficient abatement of organic contaminants.

Summary: In this study, a facile strategy was proposed to achieve efficient degradation of antibiotics by peroxymonosulfate (PMS) activation through in-situ growth of single cobalt atoms on polymeric carbon nitride (pCN). The prepared single-atom cobalt catalyst effectively catalyzed the degradation of tetracycline, with CoN/O sites serving as the active site for generating active radical species (singlet oxygen) from PMS activation. This work may expand the strategy for constructing single-atom catalysts and extend its application for the advanced oxidation process.

Summary: Catalyst-free visible light assisted Fenton-like catalysis provides opportunities for sustainable water decontamination, but the synergistic decontamination mechanisms, especially the effect of proton transfer process (PTP), are still unclear. This study detailed the conversion of peroxymonosulfate (PMS) in a photosensitive dye-enriched system. The photo-electron transfer between the excited dye and PMS triggered efficient activation of PMS and enhanced the production of reactive species. Photochemistry behavior analysis and DFT calculations revealed that PTP was the crucial factor determining the decontamination performance by transforming dye molecules, and the excitation process involved low energy excitations, with electrons and holes mainly contributed by LUMO and HOMO.

Summary: Metal components have significant impacts on the generation of persistent free radicals (PFRs) in biochar. This study investigates the effect of interactions among metal components on the formation of PFRs during biomass pyrolysis. The results show that the coupling of Fe with Co and Ni increases the abundance of PFRs in iron-containing biochars (IBCs), while Zn inhibits PFRs generation. Persulfate activation experiments confirm that PFRs are critical redox sites. NiFeO/BC is identified as a more efficient catalyst for PFRs activation. This study provides new methods for regulating PFRs in biochar and advances the understanding of metal-containing biomass pyrolysis processes.
