Inexpensive, stable, selective, and recyclable nanocatalysts, waste regeneration, utilization of safe available solvents are interest important factors in laboratory science industrial applications green chemistry. Therefore, herein, biochar nanoparticles (BNPs) were synthesized through chicken manure pyrolysis as a novel method for recycling. Then, order to improve their recyclability, the obtained BNPs magnetized using magnetic nickel nanoparticles. surface (BMNPs) was modified by (3-chloropropyl)trimethoxysilane (3-CPTMS) further neodymium Schiff-base complex immobilized on BMNPs, denoted Nd-Schiff-base@BMNPs. The supported used practical, biocompatible, commercial, reusable heterogeneous nanocatalyst. support this nanocatalyst formed from manure; therefore, it is cheap, economically viable, also compatible with principles Nd-Schiff-base@BMNPs acts selectively organic reactions can easily be recovered an external magnet reused, which This characterized wavelength-dispersive X-ray spectroscopy (WDX), scanning electron microscopy (SEM), energy-dispersive (EDS), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), inductively coupled plasma (ICP), N

Biochar-mediated remediation of uranium-contaminated soils: evidence, mechanisms, and perspectives

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: March 1, 2024

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. The modification intensifying these can promote immobilisation Finally, alleviates oxidative stress reduces tissues, thereby mitigating adverse development. Overall, our highlights capacity to remediate through diverse mechanisms, valuable insights sustainable remediation. Highlights Biochar mobility variety including limits its plants.
