Abstract ：
Para-arsanilic acid (p-ASA) is widely used as a feed additive, making it a pervasive environmental pollutant. Due to its migratory and transformative nature, p-ASA can easily convert into more toxic inorganic arsenic during its migration, thereby increasing the ecological burden and posing a threat to human health. Efficient removal of p- ASA from water is crucial for mitigating arsenic contamination. Efficient removal of p-ASA from water is crucial for mitigating arsenic contamination. This study introduced zirconium-loaded collagen fiber membrane (CFM-Zr), a novel, sustainable membrane adsorption material synthesized by retanning collagen fiber membranes (CFM) with zirconium (Zr). Leveraging the physicochemical properties of CFM and the strong affinity of Zr forp-ASA, CFM-Zr achieved highly efficient p-ASA removal. The resulting membrane was made entirely from green, low-carbon and recyclable raw materials, achieving sustainable removal of p-ASA while realizing the concept of treating waste with waste for environmental recovery. Remarkably, the retanning with zirconium significantly enhanced the Zeta potential of CFM-Zr, strengthening its electrostatic attraction to p-ASA, with a maximum adsorption capacity of 289.02 mg & sdot;g- 1, which was 19.72 times higher than that of the CFM before retanning (13.95 mg & sdot;g-1). Its adsorption rate constant was 12.54 mg & sdot;g-1 & sdot;min- 1. Moreover, CFM-Zr showed good reusability and exhibited electrostatic adsorption and metal coordination effects on the "organic" parts (-OH,-NH2) and "inorganic" parts (As-O) of p-ASA, effectively removing it. This work provided a promising bio-based material for water purification, promoted the sustainable utilization of leather industry waste, and offered significant advancements in environmental remediation and resource recovery.

Abstract ：
Depolymerizing lignin to produce high-value chemicals under mild conditions is a significant way to achieve the sustainable development of agriculture and forestry industry, and attracting a growing number of attentions. In this work, a bimetallic Ni-Co catalyst (CoNi2@BTC) was prepared by using MOF as precursor and then employed to degrade the lignin model compounds and real corncob lignin. The resulted CoNi2@BTC mainly composed of Co-0, Ni-0, Co and Ni oxides. Compared to the pure Co@BTC and Ni@BTC, CoNi2@BTC exhibited much better (4.0-4.75 times) performance on cracking the ether bonds without H-2. During the degradation of lignin model compounds, CoNi2@BTC could not only completely crack the various ether bonds (alpha-O-4, beta-O-4 and 4-O-5), but also further hydrogenate the intermediates, resulting the highly selective yield of cycloparaffin (>79.58 %) and cyclohexanol (100 %). The mechanism on ether bond cleavage was ascribed into the weakly acidic site originating from Co and the strongly acidic site stemming from Ni, while the further hydrogenation was attributed into the strong activity of Ni on activating H. Due to the synergistic effect of Ni and Co, CoNi2@BTC also exhibited full depolymerization of real corncob lignin and achieved the high selectivity of cycloparaffin (80.16 %) in the bio-oil. This work will provide a new strategy to the resource utilization of the biomass waste.

Abstract ：
Persulfate-based advanced oxidation technologies (PS-AOPs) show great potential in treating emerging pollutants because of their multiple reaction pathways induced by a variety of reactive species. However, the modulation of the reactive species in PS-AOPs and the specificity of reactive species for contaminants have still not received adequate attention. In this work, the feasibility of pH on modulating reactive species in PS-AOPs mediated by single-atom Co catalyst (CoSA) and the relationship between each species and contaminant were deeply discussed. In the CoSA/PMS system, Co(IV) was the predominantly active species in acidic conditions, and 1O2 was the predominantly active species in neutral and alkaline conditions. Specific degradation relationships with various pollutants were explored based on different major active species regulated under different pH conditions. Density Functional Theory (DFT) and experimental results demonstrated that organic pollutants with high EHOMO (Energy of the Highest Occupied Molecular Orbital), low VIP (Vertical Ionization Potential) and Delta E (Energy Gap) were susceptible to oxidative degradation. Sulfonamide compounds, phenol compounds and tetracycline compounds tended to be attacked by 1O2. And the carbamazepine compounds and quinolone compounds tended to be attacked by Co(IV). This study will provide new perspectives on reactive species regulation and specific degradation of pollutants, and offer innovative ideas for rapid remediation of emerging pollutants in aquatic environments.

Abstract ：
Developing adsorbents with high performance and long service life for effective extracting the trace organochlorine pesticides (OCPs) from real water is attracting numerous attentions. Herein, a self-standing covalent organic framework (COF-TpPa) membrane with fiber morphology was successfully synthesized by using electrospun nanofiber membranes as template and employed as solid-phase microextraction (SPME) coating for ultra-high sensitivity extraction and analysis of trace OCPs in water. The as-synthesized COF-TpPa membrane exhibited a high specific surface area (800.83 m(2) g(-1)), stable nanofibrous structure, and excellent chemical and thermal stability. Based on the COF-TpPa membrane, a new SPME analytical method in conjunction with gas chromatography-mass spectrometry (GC-MS) was established. This proposed method possessed favorable linearity in concentration of 0.05-2000 ng L-1, high sensitivity with enrichment factors ranging from 2175 to 5846, low limits of detection (0.001-0.150 ng L-1), satisfactory precision (RSD < 10 %), and excellent repeatability (>150 cycles), which was better than most of the reported works. Additionally, the density functional theory (DFT) calculations and XPS results demonstrated that the outstanding enrichment performance of the COF-TpPa membrane was owing to synergistic effect of pi-pi stacking effects, high specific surface area and hydrogen bonding. This work will expect to extend the applications of COF membrane to captures trace organic pollutants in complex environmental water, as well as offer a multiscale interpretation for the design of effective adsorbents.

Abstract ：
Detecting trace endocrine disruptors in water is crucial for evaluating the water quality. In this work, a innovative modified polyacrylonitrile@cyanuric chloride-triphenylphosphine nanofiber membrane (PAN@CC-TPS) was prepared by in situ growing triazine porous organic polymers on the polyacrylonitrile (PAN) nanofibers, and used in the dispersive solid phase extraction (DSPE) to enrich trace nitrobenzene phenols (NPs) in water. The resluted PAN@CC-TPS nanofiber membrane consisted of numerous PAN nanofibers cover with CC-TPS solid spheres (similar to 2.50 mu m) and owned abundant functional groups, excellent enrichment performance and good stability. In addition, the method based on PAN@CC-TPS displayed outstanding capacity in detecting the trace nitrobenzene phenols, with 0.50-1.00 mu g/L of the quantification, 0.10-0.80 mu g/L of the detection limit, 85.35-113.55 % of the recovery efficiency, and 98.08-103.02 of the enrichment factor, which was comparable to most materials. Meanwhile, when PAN@CC-TPS was adopted in the real water samples (sea water and river water), the high enrichment factors and recovery percentages strongly confirmed the feasibility of PAN@CC-TPS for enriching and detecting the trace NPs. Besides, the related mechanism of extracting NPs on PAN@CC-TPS mainly involved the synergistic effect of hydrogen bonding, pi-pi stacking and hydrophobic effect.

Abstract ：
An annual production of about 500 million tons of household food waste (HFW) has been documented, resulting in significant implications for human health and the environment in the absence of appropriate treatment. The anaerobic fermentation of HFW in an open system offers the potential to recover high value-added products, lactic acid (LA), thereby simultaneously addressing waste treatment and enhancing resource recovery efficiency. Most of LA fermentation studies have been conducted under mesophilic and thermophilic conditions, with limited research on the production of LA through anaerobic fermentation under hyperthermophilic conditions. This study aimed to produce LA through anaerobic fermentation from HFW under hyperthermophilic conditions (70 +/- 1 degrees C), while varying pH values (5.0 +/- 0.1, 7.0 +/- 0.1, and 9.0 +/- 0.1), and compare the results with LA production under mesophilic (35 +/- 1 degrees C) and thermophilic (52 +/- 1 degrees C) conditions. The findings of this study indicated that the combination of hyperthermophilic conditions and a neutral pH (pH7_70) yielded the highest concentration of LA, measuring at 17.75 +/- 1.51 g/L. The mechanism underlying the high yield of LA at 70 degrees C was elucidated through the combined analysis of organics dissolution, enzymes activities, and 16S rRNA microbiome sequencing.

Abstract ：
China generates over 100 million tons of food waste annually, leading to significant environmental pollution and health risks if not managed properly. Converting FW into a high-value-added platform molecule, lactic acid (LA), through fermentation offers a promising approach for both waste treatment and resource recovery. This paper presents a comprehensive review of recent advancements in LA production from FW, focusing on pure strains fermentation and open fermentation technologies, metabolic mechanisms, and problems in fermentation. It also assesses purification methods, including molecular distillation, adsorption, membrane separation, precipitation, esterification and hydrolysis, solvent extraction, and in-situ separation, analyzing their efficiency, advantages, and disadvantages. However, current research encounters several challenges, including low LA yield, low optical purity of L-(+)-LA, and difficulties in the separation and purification of LA. The integration of in-situ separation technology coupled with multiple separation methods is highlighted as a promising direction for future advancements.

Abstract ：
Eucommia ulmoides gum (EUG) with high purity was extracted directly from the Eucommia ulmoides pericarp using a biphasic solvent system consisting of deep eutectic solvent (DES) and petroleum ether. The addition of DES enabled the deconstruction of lignocellulose and the exposure of EUG, leading to the efficient dissolution of EUG in petroleum ether. The extraction rate of EUG was 22.986 %, and the purity of EUG was 98.01 %. The chemical structure of EUG was confirmed by FTIR and NMR characterization. XRD and DSC analysis reviewed the partial destruction of crystal structure and the decline of beta- crystal phase of EUG during the extraction process. Moreover, the extracted EUG exhibited high tensile strength of 10.360 MPa, excellent elongation at break of 78.663 % ascribed to the unique crystallinity that enhanced the flexibility of molecular chains. In addition, the recycling performance of DES and petroleum ether was verified, and the recovery rate were up to 94.04 % and 82.60 %, respectively, indicating that this method is expected to replace the traditional pretreatment method for extracting EUG.
