Abstract :

采用纤维素/杨梅单宁复合气凝胶(CBT)为载体,用浸渍和原位还原法制备铁负载纤维素/单宁吸附剂(Fe-CBT),使用扫描电镜、傅里叶红外光谱和X射线能谱等手段对其表征,研究了三种典型氟喹诺酮类(FQs)抗生素诺氟沙星(NOR)、盐酸洛美沙星(LOM)和盐酸左氧氟沙星(LVX)的静态吸附性能。结果表明:共存阳离子Na~+、K~+、Mg~(2+)和Ca~(2+)都对吸附过程有明显的干扰。吸附过程是自发进行的放热反应,主要为单分子层吸附,而化学吸附是主要的限速步骤。准二级和Langmuir模型能很好地拟合这种吸附行为。这种吸附剂在298 K对NOR、LOM和LVX的最大理论吸附量分别达到99.07、74.17和40.14 mg/g。NaOH和NaCl对Fe-CBT都表现出较优的洗脱效果,用NaOH和NaCl溶液4次再生后Fe-CBT对NOR的吸附能力仍高于70%。Fe-CBT对FQs的去除,主要是静电引力、表面络合、氢键和π-π堆积间的协同作用造成的。

Abstract :

The production of isolated metallic nanoparticles with multifunctionalized properties, such as size and shape, is crucial for biomedical, photocatalytic, and energy storage or remediation applications. This study investigates the initial particle formations of gold nanoparticles (AuNPs) bioproduced in the cyanobacteria Anabaena sp. using high-resolution transmission electron microscopy images for digital image analysis. The developed method enabled the discovery of cerium nanoparticles (CeNPs), which were biosynthesized in the cyanobacteria Calothrix desertica. The particle size distributions for AuNPs and CeNPs were analyzed. After 10 h, the average equivalent circular diameter for AuNPs was 4.8 nm, while for CeNPs, it was approximately 5.2 nm after 25 h. The initial shape of AuNPs was sub-round to round, while the shape of CeNPs was more roundish due to their amorphous structure and formation restricted to heterocysts. The local PSDs indicate that the maturation of AuNPs begins in the middle of vegetative cells and near the cell membrane, compared to the other regions of the cell.

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.

Porous covalent organic framework nanofibrous membrane for excellent enrichment and ultra-high sensitivity detection of trace organochlorine pesticides in water SCIE

Abstract&Keyword Cite

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.

Enhanced lactic acid production from household food waste under hyperthermophilic conditions: Mechanisms and regulation SCIE
期刊论文 | 2024 , 178 , 57-65 | WASTE MANAGEMENT
Abstract&Keyword Cite

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 :

Membrane separation strategies offer promising platform for the emulsion separation. However, the low mechanical strength of membrane separation layers and the trade-off between separation flux and efficiency present significant challenges. In this study, we report a CFM@UiO-66-NH2 membrane with high separation flux, efficiency and stability, through utilizing a robust anti-abrasion collagen fiber membrane (CFM) as the multifunctional support and UiO-66-NH2 by an in-situ growth as the separation layer. The high mechanical strength of the CFM compensated for the weakness of the separation layer, while the charge-breaking effect of UiO-66-NH2, along with the size sieving of its constituent separating layers and the capillary effect of the collagen fibers, contributed to the potential for efficient separation. Additionally, the CFM@UiO-66-NH2 membrane exhibited superhydrophilic properties, making it suitable for separating oil-in-water microemulsions and nanoemulsions stabilized by anionic surfactants. The membrane demonstrated remarkable separation efficiencies of up to 99.960% and a separation flux of 370.05 L center dot m-2 center dot h-1. Moreover, it exhibits stability, durability, and abrasion resistance, maintaining excellent separation performance even when exposed to strong acids and alkalis without any damage to its structure and performance. After six cycles of reuse, it achieved a separation flux of 417.97 L center dot m-2 center dot h-1 and a separation efficiency of 99.747%. Furthermore, after undergoing 500 cycles of strong abrasion, the separation flux remained at 124.39 L center dot m-2 center dot h-1, with a separation efficiency of 99.992%. These properties make it suitable for the long-term use in harsh operating environments. We attribute these properties to the electrostatic effect resulting from the amino group on UiO-66-NH2 and its in-situ growth on the CFM, which forms a size-screening separation layer. Our work highlights the potential of the CFM@UiO-66NH2 membrane as an environmentally friendly size-screening material for the efficient emulsion wastewater separation.

Abstract :

Biochar derived from sludge is recognized for its sustainable and cost-effective role in advanced oxidation processes, yet its restricted catalytic capacity poses significant challenges. In this work, nitrogen (8.43 at%) and sulfur (1.39 at%) co-doped biochar (ML-SDBC) featuring a large surface area of 161.14 m2/g was synthesized by the pyrolysis of sewage sludge and sulfonated lignin without external dopants. In the synthesis of ML-SDBC, graphitic nitrogen and thiophene sulfur were efficiently integrated into the carbon framework. Furthermore, the resulting biochar notably outperformed sludge-derived biochar (SDBC) in activating peroxymonosulfate (PMS) for sulfadiazine (SDZ) degradation, achieving a 31.9% higher removal rate within 120 min and exhibiting a rate constant (kobs) of 1.73x10- 2 min-1, effectively tripling the efficiency compared to that of SDBC-driven processes. The degradation rate consistently exceeded 85% across a wide pH range of 3-9. Mechanistic analysis exhibited that degradation processes involved radical and non-radical pathways, with 1O2 playing a prominent role. Furthermore, density functional theory (DFT) calculations revealed that the catalytic potential in ML-SDBC would benefit from the synergistic interaction between graphitic nitrogen and thiophene sulfur. This study presents a novel synthesis of heteroatom-doped biochar from waste, offering a sustainable solution to antibiotic pollution and waste management challenges.

Abstract :

A new nitrogen doped sinocalamus oldhami lignin-based activated biochar (denoted as N-BGAC) with a notably high adsorption efficiency was prepared for the removal of malachite green (MG). The properties and structure of N-BGAC were thoroughly characterized, alongside an investigation into the MG adsorption process. The findings revealed that N-BGAC possessed a substantial specific surface area of 2238 m(2) g(-1), nearly double that of the activated biochar lacking nitrogen doping (BGAC). Additionally, N-BGAC exhibited exceptional adsorption efficiency for MG, boasting a maximum adsorption capacity of 1372.5 mg g(-1), marking an enhancement of nearly 2.5 times compared to BGAC. By exploring the adsorption mechanism, it could be found that the adsorption process was a spontaneous exothermic reaction, and mainly controlled by pore-filling effect, electrostatic interactions, hydrogen bonding, hydrophobic interactions and pi-pi bonding interactions. Crucially, in the regeneration experiments, the removal percentage of MG could still reach 81.5% after four cycles of regeneration, making it promising in the contaminant removal.

Abstract&Keyword Cite

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.
