Bioremediation of uranium (VI)-contaminated aquifers was investigated by using bacteria isolated from a uranium tailing in South China. The bacteria were identified as Acinetobacter on the basis of physiological, biochemical tests and 16S rDNA sequence homology analysis. The protein concentration in the supernatant declined from 50.26 μ g/mL to 40.01 μ g/mL after uranium removal, and the activity of bacterial phosphatase increased from 36.04 U/L to 39.81 U/L. The FTIR, SEM-EDS and XRD demonstrated the involvement of functional groups in U (VI) binding, U accumulated on the surface of the bacteria and the precipitated is Uranyl Sulfite Hydrate. The results from this study demonstrate the potential of the U tolerant, bacterium Acinetobacter sp. USC B2 isolate might be considered as promising candidates in the design of uranium bioremediation strategies. © 2018 Institute of Physics Publishing. All rights reserved.

Thallium is an extremely toxic metal and abundant in industrial wastewater but little studied. In order to understand the optimal adsorption kinetic parameters of the chelating resin containing hydrazine wastewater, we carried out adsorption experiments on the cerium-containing wastewater treated by chemical precipitation. In this chapter, the optimum adsorption conditions, adsorption model, dynamic adsorption curve and desorption and regeneration of adsorbent were determined at different pH, temperature, adsorption time and different adsorbent dosage. The results show that the removal rate of thallium wastewater by resin is up to 97.5% when the pH value is 9. The optimum adsorption temperature is 30 and the adsorption reached equilibrium at 80 min. The adsorption process is consistent with Lagergren quasi-second-order adsorption and Langmuir isotherm model. The regenerative properties of the resin show that the resin adsorption rates still reach 95.8% after repeat use for six times. In summary, the chelating resin has good adsorption and reusability to the thallium-containing wastewater

Journal of Alloys and Compounds 2025年 1030卷

作者： Chen, Yingming Gao, Fei Li, Yali Zeng, Dong Liu, Bo Liu, Liang Guan, Jintao Gao, Chao Peng, Shuai Key Laboratory of Resources Conversion and Pollution Control of the State Ethnic Affair Commission College of Resource and Environmental Science South-Central Minzu University Wuhan430074 China School of Life Science and Technology Wuhan Polytechnic University Wuhan430023 China School of Chemical and Environmental Engineering Wuhan Polytechnic University Wuhan430023 China Department of Orthopaedics Union Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan430022 China Hubei Provincial Engineering Laboratory for Clean Production and High-Value Utilization of Bio-Based Textile Materials Wuhan Textile University Wuhan430073 China

Organic framework materials (OFs) exhibit broad prospects in the biomedical field due to their tunable structure and multifunctionality. This review systematically summarizes the classification, formation mechanisms, and synthesis strategies (such as solvothermal method and microwave-assisted method) of MOFs, COFs, and HOFs, and focuses on their innovative applications in biomedicine. Research indicates that OFs can achieve efficient drug loading through pore engineering (such as ZIF-8 delivering anticancer drugs), enhance antibacterial performance through surface functionalization (such as the ROS generation capability of Ag-MOFs), serve as high-sensitivity biosensors (such as COFs fluorescent probes), or treat cancer through photothermal effects (the application of HOFs in photothermal therapy). However, the clinical translation of OFs still faces challenges such as biocompatibility, in vivo degradation behavior, and large-scale preparation. Future research needs to focus on the design of intelligent responsive systems (such as pH/light-triggered release) and the development of multimodal treatment platforms to facilitate their transition from laboratory research to practical applications. This work not only summarizes current progress but also provides directions for addressing key bottlenecks, laying the foundation for interdisciplinary research. © 2025

Effects of arbuscular mycorrhizal fungi on the repair capacity of perennial ryegrass (Lolium perenne L.) in the uranium-containing soils

引用

IOP Conference Series: Earth and Environmental Science 2020年第1期508卷

作者： Lishan Rong Lin Xia Bin Yuan Xiaobo Lai Juntong Hu Yingjiu Liu Hunan Provincial Key Laboratory of Pollution Control and Resources Technology University of South China Hengyang 421001 P. R. China

This research inclines to study the ramification on arbuscular mycorrhizal fungi (AMF), including Glomusclaroideum (G. claroideum) and G. mosseae strains as well as the repair process of perennial ryegrass (Lolium perenne L.) in the uranium-containing soils. Three times at 120°C for an hour was required to disinfect the soil mixture. Spraying the uranium (U3O8) into the soil mixture and mixing until the ingredients were thoroughly blended, serving the purpose of obtaining the uranium-containing soil mixture with 5 mg/kg U3O8. A week later, AMF was inoculated into every flowerpot and chamber facility. Seeds of perennial ryegrass were cultivated with thirty seeds in each flowerpot or each indoor equipment in a fortnight's time. Perennial ryegrass plants tended to be harvested after sowing and meeting the conditions of 60 days. Three substances are detected by three different detection means(Photosynthetic pigments, soluble proteins, and malondialdehyde correspond to ethanol extraction method, Coomassie brilliant blue method, and thiobarbituric acid method, respectively). Additionally, testing included activities of alkaline phosphatase and succinate dehydrogenase as well. Moreover, Hitachi H-7650 transmission electron microscope performed the function of observing cellular and subcellular distributions of uranium in plant epidermal cells. Photosynthetic pigment standards of perennial ryegrass are subject to AMF, which not only has a tendency to enhance the soluble protein levels in perennial ryegrass, but also gains the possibility of holding up the uranium-induced improvement of malondialdehyde levels in perennial ryegrass. G. mosseaes is properly more efficacious than G. claroideum in the attenuation of uranium damages in cell structures of perennial ryegrass. Our results demonstrate that AMF is capable of developing the capacity of perennial ryegrass on repairing the uranium-related soil contamination.

Visible-light-driven molecular oxygen activation (MOA) is deemed as the potential route to enhance oxidation capacity of molecular oxygen, while activation efficiency is significantly impeded thanks to the deficient charge carrier separation and transfer. In this work, an atomic scale 2D/2D Schottky heterojunction is prepared using titanium carbide as 2D platform for in situ growth of 2D ultrathin bismuth molybdate nanosheet through anaerobically hydrothermal conditions. This 2D/2D Schottky heterojunction displays high performance for MOA, which is 5.56-fold higher than pristine one. The excellent activation efficiency is originated from ultrahigh charge carrier transfer channel, in which the surface charge transfer efficiency is enhanced (30.73 % vs 18.45 %) and the surface recombination constant is decreased (0.0019 s⁻¹ vs 0.0031 s⁻¹) compared to pristine one. The mechanism of photocatalytic MOA is unearthed based on experiment results and various characterizations. This study shows the great potential of atomic scale 2D/2D Schottky heterojunction in photocatalytic MOA. © 2020 Elsevier B.V.

The influence of tetracycline（TC） antibiotics on phosphine（PH3） production in the anaerobic wastewater treatment was studied. A lab-scale anaerobic baffled reactor with three compartments was employed to simulate this process. The reactor was operated in a TC-absence wastewater and 250 μg/L TC-presence wastewater for three months after a start-up period,respectively. The responses of p H, oxidation–reduction potential（ORP）, chemical oxygen demand（COD）, total phosphorus（TP）, enzymes activity（dehydrogenase and acid phosphatase）,and microbial community were investigated to reveal the effect of TC on PH3 *** suggested that the dehydrogenase（DH） activity, acid phosphatase（ACP） activity and COD have positive relationship with PH3 production, while p H, ORP level and the TP in liquid phase have negative relationship with PH3 production. With prolonged TC exposure, decrease in p H and increase in DH activity are beneficial to PH3 production, while decrease in COD and ACP activity are not the limiting factors for PH3 production.

In this study, the sediments from the Liuyang River（hunan Province, China） were used as an inoculum to bio-reduction perchlorate in a bio-electrochemical reactor（BER）. The efficient degradation of perchlorate was found in the BER by utilizing the hydrogen as electron donor. When the current intensity was 10 mA and HRT was 72 h, the removal rate of perchlorate（initial concentration was 5 mg/L） reached 84.13% and a removal flux of 178.68 mg/m·d was achieved. High-throughput sequencing analysis confirmed that the biofilm in the reactor had been successfully acclimated, and the system could achieve perchlorate reduction effectively. Firmicutes and Bacteroidetes were the dominant phyla during inoculation phase, and Actinobacteriria, Proteobacteria, and Tenericutes also constituted a low proportion in the biofilm. Bacilli and Clostridia were dominant at class-level both in inoculum and biofilm, with the relative abundance about 56%-72% and 17%-23%, respectively. These results confirmed that the biofilm in the BER system had been successfully formed, and the BER system could biodegradation perchlorate effectively.

The impact of nanoparticles (NP) mixtures (Fe + Ni + Co, Fe + Ni, Fe + Co, and Ni + Co) on the anaerobic digestion (AD) of cow manure was examined through kinetic modelling (Modified Gompertz, Logistic, and First-order kinetic) and experimental observations. The NPs mixture significantly enhanced biogas production rate and yield potential. The variation between predicted and actual biogas yields was smaller with the Modified Gompertz model (1.37% to 5.30%) and First-order kinetic model (0.04% to 3.83%) compared to the Logistic model (1.99% to 7.04%). Additionally, digestates containing NPs showed strong fertility properties (5.16% to 5.36%). The combined use of kinetic models and experiments offers an effective way to quantify the influence of NPs mixture on AD performance, aiding in industrial application.
