A review on As-contaminated soil remediation using waste biomass feedstock-based biochar and metal-modified biochar

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 292, P. 117927 - 117927

Published: March 1, 2025

Arsenic (As) is a carcinogen that threatens ecosystems and human health. Due to its high adsorption, microporosity, biochar widely available for soil remediation. This review significantly summarizes the current status of waste biomass feedstock-based metal-modified As-contaminated Firstly, this paper briefly describes sources hazards As in soil, secondly, lists eleven feedstocks preparing biochar. Agricultural, domestic, forestry wastes provide plentiful source preparation. Single or multi-metal modifications such as iron (Fe), manganese (Mn), cerium (Ce) can effectively improve Arsenite [As(III)] arsenate [As(V)] adsorption capacity The primary mechanisms removal by include ion exchange, electrostatic attraction, surface complexation, redox transformation, H-bond formation. In conclusion, presents an in-depth discussion on both metal modification, providing constructive suggestions future development remediate soil.

Arsenic removal from contaminated water using adsorptive electrospun nanofibrous membrane of polyacrylonitrile/organoclay

Polymer Engineering and Science, Journal Year: 2024, Volume and Issue: 64(10), P. 4850 - 4860

Published: Aug. 27, 2024

Abstract Adsorptive nanofiber electrospun membranes (ANEMs) show promise for heavy metal removal, particularly in dilute solutions. Nanofibrous polyacrylonitrile (PAN) incorporating Cloisite 20A (C20) organoclay were fabricated via electrospinning As(V) removal. The impact of C20 on structural properties and removal efficiency the was investigated. results indicated that PAN‐C20 morphology uniform, with fiber diameters mostly falling within 100–300 nm range. Incorporation C20, especially an exfoliated structure, led to increased hydrophilicity, mechanical strength, roughness membranes. Batch adsorption revealed adding up 1.5 wt.% significantly enhanced capacity due higher concentration proper dispersion. Dynamic filtration showed PAN‐C20(1.0) membrane achieved over 90% 960 min demonstrated excellent regeneration ability. Highlights incorporated into PAN by prepare adsorptive membrane. used from water. Type dispersion dynamic more important than static PAN‐C20‐1.0 structure intercalated structure. usable multiple adsorption–desorption cycles.

Arsenic Contamination in Sludge and Sediment and Relationship with Microbial Resistance Genes: Interactions and Remediation

Water, Journal Year: 2024, Volume and Issue: 16(24), P. 3633 - 3633

Published: Dec. 17, 2024

Arsenic contamination in sludge and sediment has emerged as a pressing environmental issue with far-reaching implications. This review delves into the multifaceted problem of arsenic contamination, focusing on its complex interactions microbial resistance genes (MRGs). It explores key role microorganisms biogeochemical cycling arsenic, including processes such reduction, oxidation, methylation, volatilization. describes how resist through that encode proteins efflux pumps, enzymatic detoxification, intracellular sequestration. Arsenic, naturally occurring element, can enter various natural anthropogenic pathways, leading to detrimental effects quality. Understanding mobilization, transformation, their ability toxicity MRGs is essential for effective mitigation remediation strategies. discusses sources distribution sediment, intricate mechanisms resistance, potential implications management human health. also examines current research trends identifies areas requiring further investigation. By unraveling interplay between microorganisms, MRGs, this aims contribute deeper understanding guide future protection efforts.
