Abstract ：
光响应性吸附材料对污染物的光控释放性能，对发展吸附材料的绿色再生具有重要的意义。以纤维素为原料，偶氮苯衍生物为功能单体，以典型农药残留2,4-D为模板，采用表面引发原子转移自由基聚合（SI-ATRP）制备光响应纤维素印迹吸附剂（Cell-AB-MIP）。通过单因素实验对材料的制备条件进行优选，采用多种表征手段对材料结构和性能进行分析。结果表明：Cell-AB-MIP表面含有丰富的官能团（—COOH,N=N等），对2,4-D具有较高的特异性识别作用；偶氮苯基团的引入使得Cell-AB-MIP具备优异的光再生性能。经过紫外光照射后，Cell-AB-MIP上的偶氮苯基团将从反式构型转变为顺式构型，从而改变吸附剂对污染物的吸附亲和力，实现光控条件下的清洁脱附。在甲醇介质中光照解吸效率可达72.22%，经过5次光循环后对2,4-D的吸附百分比仍可达到83.47%;SEM及EA分析结果证实了吸附剂经紫外光照射后污染物可从吸附剂表面脱离，完成吸附剂的再生过程。

Abstract ：
Developing the transition metal catalysts with high reactivity for the sulfate radical (SO4 -center dot) based advanced oxidation processes (SR-AOPs) has been attracting numerous attentions. To improve the peroxymonosulfate (PMS) activation process mediated by Co-based catalysts, a vanadium-cobalt bimetallic catalyst (V@CoO) was fabricated by modification vanadium through a simple solvothermal method. The pollutants degradation experiments showed that the obtained V@CoO exhibited much higher performance on PMS activation (5.55-8.33 times larger of apparent rate constants) than pure CoO, and the V@CoO/PMS system could quickly degrade various organic contaminants within 5 min under the attack of both radicals (SO4 -center dot and O2-center dot) and non-radicals (1O2). The density functional theory (DFT) calculations and electrochemical tests revealed that the enhancing mechanism of V modification involved four aspects: (i) promoting the PMS adsorption on the surface of V@CoO; (ii) enhancing the electron transfer efficiency between V@CoO and PMS; (iii) activating PMS with V3+ and V4+ species; (iv) accelerating the circulation of Co2+ and Co3+, leading to the promotion on the production of reactive oxygen species (ROS). Furthermore, the V@CoO/PMS system also exhibited satisfactory stability in a broad pH range and good efficiency in the presence of co-existing components (HCO3-, NO3-, PO43- , Cl- and HA) in water. This study will provide new insights to designing high-performance, environment-friendly bimetal catalysts and some basis for the remediation of organic contaminants with SR-AOPs.

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 ：
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 ：
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 ：
A boron and iron co-doped biochar (B-Fe/biochar) from Masson pine bark was fabricated and used to activate peroxydisulfate (PDS) for the degradation of guaiacol (GL). The roles of the dopants and the contribution of the radical and non-radical oxidations were investigated. The results showed that the doping of boron and iron significantly improved the catalytic activity of the biochar catalyst with a GL removal efficiency of 98.30% within 30 min. The degradation of the GL mainly occurred through the generation of hydroxyl radicals (center dot OHs) and electron transfer on the biochar surface, and a non-radical degradation pathway dominated by direct electron transfer was proposed. Recycling the B-Fe/biochar showed low metal leaching from the catalyst and satisfactory long-term stability and reusability, providing potential insights into the use of metal and non-metal co-doped biochar catalysts for PDS activation.

Abstract ：
As the cheap and efficient catalysts, the iron-based catalysts have been considered as one of the most promising catalysts for peroxydisulfate (PDS) activation and the development of high-performance iron-based catalysts are attracting growing attentions. In this work, a magnetic Fe-based catalysts (Fe/NC-1000) was obtained by using Fe modified ZIF-8 as the precursor and used to activate the PDS for the degradation of perfluorooctane sulphonate (PFOS). Morphology and structure analysis showed that the resulted Fe/NC-1000 catalyst was displayed porous spheres (40-60 nm) and mainly composed of Fe0, FeNx and carbon. When Fe/NC-1000 was employed to activate the PDS (0.1 g/L of catalyst dosage, 0.5 g/L of PDS dosage and at initial pH of 4.6), the Fe/NC-1000/PDS system exhibited excellent efficiency (97.9 & PLUSMN; 0.1) % for PFOS (10 mg/L) degradation within 30 min. The quenching tests and EPR results revealed that the Fe/NC-1000/PDS system degraded PFOS primarily through singlet oxygen (1O2) evolution and electron-transfer process. Besides, based on the degradation byproducts determined by LC-MS-MS, the PFOS first occurred de-sulfonation to form PFOA, and then the resulted PFOA underwent stepwise defluorination in the Fe/NC-1000/PDS system. Density Functional Theory (DFT) calculations and electrochemistry tests strongly confirmed that Fe/NC-1000 exhibited high electron transfer efficiency, resulting in promoted performance on activating PDS. Importantly, the results of Ecological Structure-Activity Relationship (ECOSAR) analysis showed that the intermediates were lowly toxic during the PFOS degradation, manifesting a green process for PFOS removal. This study would provide more understandings for the persulfate activation process mediated by Fe-based catalysts for Perfluorinated alkyl substances (PFAS) elimination.
