Published: Aug. 13, 2024

Heavy metal ion wastewater is a pressing and inescapable issue that closely related to human health ecological security due its toxicity, carcinogenicity, the unmanageable property of this type wastewater. Metal–Organic Frameworks (MOFs) are class crystalline nanoporous materials with flexible designability controllability, showing great potential in field adsorption purification heavy metals In Perspective, we first discuss harm different ions briefly expound virtues MOFs for pollutant adsorption. Then, mainly summarize recent advances construction metal-based (Zr-based, Zn-based, Co-based, Al-based, etc.) their research progress Furthermore, various types MOF additives can often be effectively applied by functional modification or other composition. Additionally, several commonly used kinetics isotherm models also detailed help an in-depth understanding mechanism. Finally, challenges opportunities additionally discussed, review may provide new insight water applications.

Air Bubbling Assisted Soil Washing to Treat PFAS in High Organic Content Soils

Environments, Journal Year: 2025, Volume and Issue: 12(1), P. 20 - 20

Published: Jan. 12, 2025

The soil-washing technique has been successfully utilized for the remediation of PFAS-contaminated soils. Prior studies have shown that organic carbon (OC) content and grain size soil determined efficiency PFAS removal during washing. However, most past focused on soils with a low OC content, typically ranging from 0–3%. In this study, we explored use novel process where washing was combined air bubbling (or foam fractionation) to aid in high OC-content (~4–20%). Treatment (~20%) perfluorobutane sulfonate (PFBS) perfluorooctanoate (PFOA) did not enhance their removal, as they featured surface activity. observed an improvement extraction perfluorooctane (PFOS) 27% 42% bubbling, consistent higher activity PFOS compared PFOA PFBS. Perfluorodecanoic acid (PFDA) irreversibly adsorbed removed efficiently by both A slight PFDA (6–13%) when co-surfactant (cetyltrimethylammonium chloride) added reduced ~4% addition nonorganic sand contaminated prior This suggested interaction dominant factor determining its soil. conclusion, our results indicated alone sufficient short-chain Although had mild effect some long-chain solution, it help overall soils, highlighting difficulty treatment immobilization would be ideal approach managing such sites.
