Fabrication of straw-based graphene aerogels for oil/water separation: the effects of crude fiber fractions in straw

引用

Environmental Science and pollution Research 2025年第1期32卷 43-55页

作者： Dan, Hongbing Gao, Yue Wei, Xianxiao Yue, Qinyan Gao, Baoyu Shandong Provincial Key Laboratory of Water Pollution Control and Resource Reuse School of Environmental Science and Engineering Shandong University Jinan250100 China

Benefiting from its abundance, eco-friendliness, and sustainability, crop straw is considered a promising candidate combined with graphene oxide (GO) to fabricate straw-based graphene aerogels (SGAs) for oil/water separation. However, considering the complex composition of straw, the roles played by different crude fibers in straw in the formation of SGAs are still unclear. Herein, wheat straw (WS) was used in this work and pretreated with acid and alkali to regulate its crude fiber fractions. Then, it was crosslinked with GO to fabricate various SGAs for comparing their differences in the formation, structure, and oil/water separation performance. Results indicated that acid can remove plentiful hemicellulose from the WS (from 29.9 ± 2.1 to 7.0 ± 0.8 wt%) while retaining most lignin and cellulose;alkali can retain cellulose (from 32.4 ± 3.6 to 70.6 ± 1.3 wt%) while greatly removing lignin and hemicellulose. Ascribed to high BET surface area and porous structure, the graphene aerogels formed by acid-/alkali-treated WS demonstrated superior oil absorption capacity (AC-WSGA: 62.3–126.0 g/g and AL-WSGA: 66.3–125.2 g/g). The poor mechanical compressibility of AC-WSGA was caused by the high lignin residue (16.2 ± 0.7 wt%) in AC-WS. The maximum compressive stress for AL-WSGA under 60% strain was 1.6 kPa, ensuring it achieved recoverable oil-absorbing properties by extrusion. The above findings suggested that cellulose and hemicellulose in straw contributed to the formation of SGAs with abundant porous and compressible architecture, whereas the presence of lignin greatly increased the brittleness of SGAs and decreased their oil removal and recycling performances. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Studying the combined phytotoxicity of PFOA with Fe2O3 or MnO2 nanoparticles (NPs) is paramount for addressing the remediation of PFOA-contaminated agricultural soils and assessing the efficacy of nanoparticle-assisted phytoremediation strategies. By exposing radish plants to PFOA with/without Fe2O3 or MnO2 NPs for 60 days, this study delved into radish biomass, PFOA accumulation, chlorophyll pigments, antioxidant defenses, and nutrient contents. key findings showed that PFOA at environmentally relevant levels (20 μg/kg) were highly toxic to radish plants. PFOA accumulated significantly in radish organs, especially in the shoots. Additionally, PFOA exposure had a detrimental impact on radish growth. However, the application of Fe2O3 and MnO2 NPs facilitated the translocation of PFOA up to shoots, thereby reducing its accumulation in the edible roots. Additionally, they could significantly increase radish biomass and mitigate the damages caused by PFOA, evidenced by lower MDA contents and higher amino acid contents. This study highlights the potential of nanoparticle-enhanced phytoremediation as an effective approach for PFOA-polluted agricultural soils. By promoting the translocation of harmful pollutants away from edible plant parts and enhancing plant growth and resilience, Fe2O3 and MnO2 NPs offer a promising avenue for sustainable soil remediation strategies. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2025.

Agricultural soil is related to food security and human health, antibiotics and heavy metals (HMs), as two typical pollutants, possess a high coexistence rate in the environmental medium, which is extremely prone to inducing antibiotic-HMs combined pollution. Recently, frequent human activities have led to more prominent antibiotics-HMs combined contamination in agricultural soils, especially the production and spread of antibiotic resistance genes (ARGs), heavy metal resistance genes (MRGs), antibiotic resistant bacteria (ARB), and antibiotics-HMs complexes (AMCs), which seriously threaten soil ecology and human health. This review describes the main sources (Intrinsic and manmade sources), composite mechanisms (co-selective resistance, oxidative stress, and Joint toxicity mechanism), environmental fate and the potential risks (soil ecological and human health risks) of antibiotics and HMs in agricultural soils. Finally, the current effective source blocking, transmission control, and attenuation strategies are classified for discussion, such as the application of additives and barrier materials, as well as plant and animal remediation and bioremediation, etc., pointing out that future research should focus on the whole chain process of "source-process-terminal", intending to provide a theoretical basis and decision-making reference for future research. © 2024 Institute of Process Engineering, Chinese Academy of Sciences

Nitrogen-removed organic matters from cyanobacterial decomposition promote the release of nitrogen from lake sediment

Cyanobacterial blooms, which carry a lot of nitrogen (N) and phosphorus (P), have emerged as one of the most severe environmental issues in freshwater ecosystems. However, there are few studies on the effect of organic matters released during cyanobacterial decomposition in promoting N release from lake sediments that remain underexplored. An essential step is to eliminate the impact of the N contributions from cyanobacteria when evaluating sedimentary N release. The response surface methodology (RSM) was developed to optimize the struvite precipitation model, and the results indicated that 1.3 of Mg/N, 1.0 of P/N, and pH 9.5 were the optimum conditions for N removal from cyanobacterial pyrolysis liquid. Following this, calcium phosphate crystallization (at pH 10 and Ca/P = 4.98) removed residual P, and zeolite adsorption (at pH 8 and 10 g/L zeolite dosage) eliminated the remaining N. Ultimately, 99.3% of N was removed with the two methods in cyanobacterial pyrolysis liquid. The cyanobacterial pyrolysis liquid, stripped of N, was found to significantly enhance the release of N from lake sediment under anaerobic conditions, which can then be reutilized by cyanobacteria. These findings reveal that organic matter derived from cyanobacterial decomposition promotes sedimentary N release, creating a feedback loop that sustains cyanobacterial blooms in freshwater ecosystems. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.
