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

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.

We report an unprecedented, efficient nickel-catalysed radical relay for the remote cross-electrophile coupling of β-bromo-α-benzylamino acid esters with aryl bromides via 1,4-aryl migration/arylation cascades. β-Bromo-α-benzylamino acid esters are considered as unique molecular scaffolds allowing for aryl migration reactions, which are conceptually novel variants for the radical Truce–Smiles rearrangement. This reaction enables the formation of two new C(sp 3 )−C(sp 2 ) bonds using a bench-stable Ni/bipyridine/Zn system featuring a broad substrate scope and excellent diastereoselectivity, which provides an effective platform for the remote aryl group migration and arylation of amino acid esters via redox-neutral C(sp 3 )−C(sp 2 ) bond cleavage. Mechanistically, this cascade reaction is accomplished by combining two powerful catalytic cycles consisting of a cross-electrophile coupling and radical 1,4-aryl migration through the generation of C(sp 3 )-centred radical intermediates from the homolysis of C(sp 3 )−Br bonds and the switching of the transient alkyl radical into a robust α-aminoalkyl radical.

Developing novel coating materials for fast and sensitive solid-phase microextraction(SPME) is highly desired but few are achieved. A new material of metal-organic framework(MOF)-derived hollow carbon nanocubes(HCNCs) was prepared as a fiber coating material for SPME. The HCNCs-coated fiber(denoted as HCNCs-F) exhibited a better enrichment performance than solid carbon nanocubes(SCNCs)-coated fiber(denoted as SCNCs-F) and commercial fibers based on the abundant active sites of the hollow structure, hydrophobic interactions, and π-π interactions. Moreover, because of the reduced mass-transport lengths of the hollow mesoporous structure, the HCNCs-F demonstrated a faster mass transfer compared with the SCNCs-F. The HCNCs-F was used to determine the six hydrophobic polycyclic aromatic hydrocarbons(PAHs) with wide linear ranges, good reproducibility, and low detection limits. Finally, the HCNCs-F was successfully applied for the determination of PAHs from the real water samples.

Soil organic nitrogen (SON) decomposition is a fundamental process in the nitrogen (N) cycle that influences N availability for plant uptake and soil health. However, the long-term effects of nutrient fertilisation on SON decomposition and its microbial drivers remain poorly understood. Here, we used the 180-year-old Broadbalk Winter Wheat Experiment to investigate how farmyard manure (FYM), mineral fertiliser (NPK), and no fertilisation input (NIL) affect crop yield, SON turnover, microbial community composition, and functional genes. Our findings showed that distinct and complementary microbial mechanisms regulate SON decomposition under different nutrient fertilisation treatments. FYM application increased gross N mineralisation to 43.1 mg N kg−1 soil d−1, by doubling microbial biomass and promoting bacterial-dominated protein and peptide decomposition. During the early stage of decomposition, CO2 release from protein and peptide turnover under FYM increased by 96 % and 44 %, respectively, compared to NIL. NPK fertilisation enhanced the decomposition of complex N compounds and promoted the turnover of high-molecular-weight N to support microbial growth by upregulating N-cycling genes and extracellular enzyme production. The carbon use efficiency of protein was increased to 0.68. NPK fertilisation also stimulated fungal and Actinobacteria populations, accelerating the turnover rate of peptides and amino acids to 22.7 and 2.4 mg N kg−1 soil d−1, respectively. These results provide new insights into how nutrient fertilisation practices affect microbialy-mediated N dynamics and crop productivity, emphasising the importance of microbial functional diversity in supporting soil N cycling and fertility. © 2025 Elsevier Ltd

Bentonite is a natural and environmentally clay mineral, and bentonite-derived mesoporous materials (BDMMs) were obtained conveniently from the alkali and acid treatment of bentonite. In the present study, BDMMs were explored for immobilization of laccase obtained from Trametes versicolor. As a result, bentonite-derived mesoporous materials-Laccase (BDMMs-Lac) was developed for the removal of tetracycline (TC). The enzyme immobilization process was carried out through physical adsorption contact (ion exchange adsorption, hydrogen bond adsorption, and Van der waals adsorption) between the BDMMs and laccase. The process of immobilization remarkably increased its operating temperature. The BDMMs-Lac exhibited over 60% removal efficiency for TC within 3 h in the presence of 1-hydroxybenzotriazole (HBT). In conclusion, BDMMs-Lac showed more promising potential than free laccase for practical continuous applications.

In order to verify the feasibility of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application, this study conducted the treatment processes at full-scale by physicochemical and spectral characterization. The full-scale studies showed that 48.17% of the dissolved organic carbon（DOC） and 42.27% of the dissolved organic nitrogen（DON） were removed by the microelectrolysis-Fenton oxidation process, respectively. Spectra analysis further suggested that the mature leachate was mainly composed of tryptophan-like and fulvic-like compounds. The combination of microelectrolysis and Fenton oxidation efficiently decomposed the aromatic C=C into carboxyl-C and decreased the molecular size of DOC, resulting in a dramatic reduce（97.1%-98.3%） of the fluorescence intensity. The DON removal by microelectrolysis-Fenton oxidation likely associated with the NH-decomposition of tryptophan-like and aromatic compounds into NO-N. The tryptophan-like compounds may play a dominant role in Ba binding, while Pb and Cd were likely bound to both the tryptophan-like and fulvic-like compounds. Above 60% of the heavy metals were removed in the microelectrolysis-Fenton oxidation section. Results above confirmed the effectiveness of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application.
