Key adsorbents and influencing factors in the adsorption of micro- and nanoplastics: A review

Journal of Environmental Management, Journal Year: 2025, Volume and Issue: 383, P. 125394 - 125394

Published: April 22, 2025

Microplastics and nanoplastics (MNPs) are emerging contaminants in drinking water sources that pose serious risks to human health ecosystems. Several removal strategies, such as adsorption, exist but present challenges for their industrial scalability. This review provides a concise overview of MNP adsorption mechanisms highlights the limited critical exploration column literature, emphasizing its importance large-scale applications. Special attention is given carbon-based materials due cost-effectiveness, environmental friendliness sustainability. Other adsorbents (e.g., metal-organic frameworks, clays) also discussed promising performance realistic matrixes. To predict optimize efficiency adsorbents, leading simulation models reviewed. Taken together, this work comprehensive fundamental factors, mechanisms, adsorbent selection experimental conditions, adsorption. By highlighting underexplored area column-based processes, it valuable information advance viable industrial-scale solution contamination.

Wood Gasification Biochar as an Effective Biosorbent for the Remediation of Organic Soil Pollutants

Soil Systems, Journal Year: 2025, Volume and Issue: 9(1), P. 18 - 18

Published: Feb. 24, 2025

A biochar (BC) generated by the pyrogasification of wood chips from authorized forestry cuts was extensively characterized and evaluated for its efficacy in retaining/releasing two agrochemicals, namely fungicide penconazole (PEN), herbicide S-metolachlor (S-MET), xenoestrogen bisphenol (BPA) widely present industrial effluents. The elemental composition BC using CN analysis total reflection X-ray fluorescence (TXRF) spectroscopy which showed abundance elements typically found BCs (Ca, K, P) along with essential trace such as Fe Mn. Scanning electron microscopy coupled energy-dispersive (SEM-EDX) described surface features major elements, while Brunauer–Emmett–Teller (BET) revealed, expected, a large specific area (366 m2 g−1). High porosity (0.07 cm3 g−1) demonstrated density functional theory (DFT) method, Fourier transform infrared (FT-IR) highlighted presence prominent aromatic structure reactive groups responsible binding compounds. sorption/desorption capacity studied means sorption kinetics isotherms batch trials, modeling experimental data various theoretical equations. All compounds reached equilibrium on very rapidly, following preferentially pseudo-second-order kinetics. Freundlich adsorption constants PEN, S-MET, BPA were 37.3, 13.2, 11.6 L g−1, respectively, thus demonstrating great affinity hydrophobic pollutants. process hysteretic only small fraction each compound slowly desorbed BC. overall results obtained potential acting biosorbent contaminants, is importance containment pollution agricultural soils limiting entry toxic into human animal food chain.
