A Critical Review on PFAS Removal from Water: Removal Mechanism and Future Challenges

Sustainability, Год журнала: 2023, Номер 15(23), С. 16173 - 16173

Per and polyfluoroalkyl substances (PFAS) have been extensively employed in a broad range of manufacturing consumer goods due to their highly persistent nature. PFAS exposure is recognized pose serious health hazards; therefore, addressing pollution water has become top priority for public environmental protection organizations. This review article focuses on the efficiency different removal techniques (activated carbon, biochar, ion exchange resin, membrane filtration, reverse osmosis, metal-organic frameworks, foam fractionation, ozone destruction techniques) eliminating types short- long-chain from water. Hydrophobicity electrostatic interactions are revealed be primary mechanisms elimination PFAS. The all eradicate short-chain comparatively lower compared most efficient but some drawbacks, including formation precursors high operational costs. According findings study, it anticipated that combined methods will required effectively remediate PFAS-contaminated

Non-conventional sorption materials for the removal of legacy and emerging PFAS from water: A review

Emerging contaminants, Год журнала: 2024, Номер 10(3), С. 100303 - 100303

Опубликована: Фев. 8, 2024

and polyfluoroalkyl substances (PFAS) are a class of ubiquitous, persistent, hazardous pollutants that raise concerns for human health the environment. Typically, PFAS removal from water relies on adsorption techniques using conventional sorption materials like activated carbons (ACs) ion exchange resins (IERs). However, there is continuous search more efficient performing adsorbent to better address wide range chemical structures in environment, increase their selectivity, achieve an overall high capacity faster uptake kinetics. In this context, results application non-conventional (i.e., readily available biological-based proteins advanced nanocomposites cyclodextrins) reported discussed consideration following criteria: i) efficiency kinetics legacy (e.g., PFOA, PFBA) as well newly-introduced emerging GenX), ii) representativity environmental conditions experimental setup use environmentally relevant concentrations), iii) regenerability, reusability applicability materials, iv) role material modifications adsorption. From review, it emerged organic frameworks, nano(ligno)cellulosic-based layered double hydroxides among most promising herein investigated adsorption, was also observed presence fluorine- amine-moieties structure improve both selectivity uptake. lack data real environments costs involved means research still its infancy need further investigation.

The increasing health risks posed by per- and polyfluoroalkyl substances (PFASs) in the environment highlight importance of implementing effective removal techniques. Conventional wastewater treatment processes are inadequate for removing persistent organic pollutants. Recent studies have increasingly demonstrated that metal–organic frameworks (MOFs) capable PFASs from water through adsorption However, there is still constructive discussion on potential MOFs adsorbing large-scale engineering applications. This review systematically investigates use as adsorbents PFAS treatment. primarily involved a comprehensive analysis existing literature to understand mechanisms identify factors enhance their efficiency PFASs. We also explore critical aspects regeneration stability MOFs, assessing reusability long-term performance, which essential Finally, our study highlights challenges using MOFs. Especially, efficient short-chain with hydrophilicity major challenge, while medium- long-chain frequently susceptible being captured multiple synergistic effects. ion-exchange force may be key solving this difficulty, but its susceptibility ion interference needs addressed practical hope can provide valuable insights into well advance sustainable utilization field treatment, thereby presenting novel perspective.
