Soil contamination with heavy metals presents a substantial environmental peril, necessitating the exploration of innovative remediation approaches. This research aimed to investigate efficiency nano-silica in stabilizing calcareous metal-contaminated soil. The soil was treated five levels 0, 100, 200, 500, and 1000 mg/kg incubated for two months. results showed that had specific surface area 179.68 $${\text{m}}^{2}/\text{g}$$ . At mg/kg, DTPA-extractable concentrations Pb, Zn, Cu, Ni, Cr decreased by 12%, 11%, 11.6%, 10%, 9.5% compared controls, respectively. Additionally, as application rate increased, both pH increased. augmentation adsorbent led decline exchangeable (EX) carbonate-bound fractions Cr, while distribution bonded Fe–Mn oxides, organic matter, residue use resulted an 8.0% reduction EX 4.5% 7.3% 7.1% 7.9% control treatment. Overall, our study highlights potential nano silica promising strategy addressing metal pollution contaminated soils, offering sustainable solutions restoration ecosystem protection.

Magnetic Layered Double Hydroxide Nanocomposites: Synthesis, Catalytic Performances, Environmental and Biological Applications

Energy & environment materials, Год журнала: 2025, Номер unknown

Опубликована: Май 28, 2025

In the present review, we addressed synthesis and applications of magnetic layered double hydroxide nanocomposites in different scientific areas including catalysis, environmental remediation, biological functions. First, appraised varied approaches for hydroxides (LDHs), containing co‐precipitation, hydrothermal, sol–gel, ion‐exchange, urea hydrolysis, reconstruction methods. Afterward, concentrated on utility LDH‐based composites evaluated their catalytic effectiveness 4‐nitrophenol reduction, coupling reactions, preparation polycyclic aromatic compounds, oxidation reactions. Next, applicability LDHs was assessed removal water pollutants dyes. Ultimately, discussed efficiency LDH like drug delivery. Investigating obtained results reviewed reports demonstrated auspicious performance these compounds all above‐mentioned fields. Overall, manifested a satisfactory outlook various due to stability, remarkable flexibility, relatively proper surface area, appropriate adsorption capacity, as well propitious retrievability reusability character.
