Coupled Influence of Magnetic Biochar and Solution Chemistries on Retention and Release of Nanoplastics in Porous Media

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(5), С. 2207 - 2207

Magnetic biochar (MBC), as an environmentally friendly material, has been extensively used for the remediation of soil and groundwater contamination. The retention release nanoplastics (NPs) with carboxyl (NPs-COOH) or amino functionalization (NPs- NH2) in saturated porous media were investigated under varying conditions ionic strength (IS), MBC addition, humic acid (HA) concentration, cation types. reversible irreversible NPs was examined by altering IS, increasing solution pH, inducing exchange. results revealed that enhanced surface roughness media, thereby inhibiting NPs' transport. HA promoted NPs-NH2 transport more effectively than NPs-COOH due to electrostatic repulsion, steric hindrance, competition deposition sites. Under a reduced IS increased portion retained released, showing greater NPs-COOH, indicating retention. Additionally, stronger charge-shielding cation-bridging effects Ca2+ significantly NPs. Cation exchange resulted less being most irreversibly deeper primary minima. However, small number remobilized electrical double layer expansion, deprotonation, exchange, These findings provide valuable insights into fate environment.

Biochar-based adsorption technologies for microplastic remediation in aquatic ecosystems

AIP Advances, Год журнала: 2025, Номер 15(3)

Опубликована: Март 1, 2025

Since microplastic (MP) particles pose serious dangers to human and environmental health by infiltrating aquatic habitats, soils, even the food chain, MP contamination has emerged as a major problem. Developing implementing efficient sorption techniques is essential lessening effects of pollution, which becoming more common. Innovative solutions are required since traditional removal frequently struggle effectively capture MPs, especially smaller particles. An overview origins processes contamination, possible effects, difficulties in identifying them biological systems given this article. One adaptable method for eliminating MPs from environments adsorption technology. Because its large surface area, complex porosity, strong stability, biochar become viable option among sorbents. Systems based on provide an economical sustainable way reduce makes important area further study. The potential rehabilitation highlighted review, also argues wider incorporation into management procedures. review affirms danger that represent ecosystems living organisms, but it points out there still gaps our understanding their consequences. Despite presentation cost-effective promising adsorbent, work maximize efficiency, optimize use, incorporate industrial-scale operations. To properly handle escalating problem these developments crucial.
