Wastewater remediation is of paramount importance for the water-stressed modern civilization from perspective sustainable development and management limited freshwater resources. Contaminants such as heavy metal metalloid ions, toxic dyes, pathogenic microbes present in aquatic ecosystem have adverse effects not only on environment but also human health. Traditional wastewater processes are costly, energy-consuming, less efficiency removing pollutants wastewater. Multi-phasic nanomaterials or nanocomposites enormous potential contaminants water bodies. These materials an tunable surface area interacting with target toxicants extremely stable system, they readily agglomerate. Many research groups exploited biosorption, bioleaching, bioprecipitation capacities fungal hyphae remediation. Recently, researchers attempted to explore synergistic effect bionanocomposite This has already shown promise a superior material treatment can easily be separated polluted reuse over several cycles. The bionanocomposite-mediated decontamination lead total paradigm shift strategies.

Abstract Herein, a biochar-based composite (Ti 3 C 2 T x @biochar-PDA/PEI) was constructed by decorating Ti and polydopamine on coconut shell biochar via electrostatic self-assembly method. Different characterization techniques were applied to explore the structure, morphology composition of sorbents. It found that higher porosity diverse functional groups conducive for @biochar-PDA/PEI capture radionuclides, water environmental conditions made great contribution adsorption process. The process removing U(VI)/Cs(I) well complied with Langmuir isotherm Pseudo-second-order equations, which indicated single layer chemical occurred solid liquid interface. Meanwhile, this produced exhibited superior removal performance under complex co-existing ion environment, maximum amounts U(VI) Cs(I) reached up 239.7 40.3 mg g −1 . Impressively, adsorbent still good after three cycles regeneration. spectral analysis DFT calculation demonstrated might be process, while should exchange or attraction.

Abstract Soil contamination by uranium presents a burgeoning global environmental concern, exerting detrimental effects on both agricultural production and soil health. Biochar, carbonaceous material derived from biomass pyrolysis, exhibits considerable potential for remediating uranium-contaminated soils. However, comprehensive review of the biochar fate accumulation in soil–plant systems remains conspicuously absent. In this paper, sources are reviewed, impact immobilization detoxification is analyzed. We reviewed status soils globally found that mining activities currently main sources. Further meta-analysis revealed addition significantly reduced bioavailability shoot accumulation, their effect value 58.9% (40.8–76.8%) 39.7% (15.7–63.8%), respectively. Additionally, enhances microenvironment, providing favourable conditions promoting plant growth reducing mobility. focused mechanisms governing interaction between uranium, emphasising roles played surface complexation, reduction, ion exchange, physical adsorption.
