At present, the defluorination of per- and polyfluoroalkyl substances (PFASs), including perfluoroether compounds as substitutes perfluorooctanoic acid (PFOA) perfluorooctanesulfonate, is limited by effective active species produced during oxidation-reduction process. The contribution hydrogen radical (•H) a companion substance in photoreduction electrocatalytic degradation PFASs has been neglected. Herein, we demonstrate that perfluorocarboxylic acids such PFOA hexafluoropropylene oxide...
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) have attracted increasing concerns owing to their potential ecotoxicological effects. The sorption of PFASs, i.e. perfluorooctanoic acid (PFOA), perfluorooctane sulfonic (PFOS), perfluorobutanoic (PFBA) perfluorobutansulfonic (PFBS), by granular activated carbon (GAC) softwood-derived biochar was studied. equilibrium PFASs on GAC obtained within 3–24 h, while the time required reach for 12–48 h. both were well represented...
Per- and polyfluoroalkyl substances (PFAS) make up a diverse group of industrially derived organic chemicals that are significant concern due to their detrimental effects on human health ecosystems. Although other technologies available for removing PFAS, adsorption remains viable effective method. Accordingly, the current study reported novel type graphene oxide (GO)-based adsorbent tested removal performance toward PFAS from water. Among eight adsorbents tested, GO modified by cationic...
Contamination of soils with poly- and perfluoroalkyl substances (PFAS) has been reported worldwide stabilization is recognized as an effective approach for in situ remediation. In this study, biochar, GAC, RemBind® 100, 100X were evaluated respect to their performance stabilizing 10 PFAS soil. The results indicated that compared unamended controls, decreased the water acidic leachable by 99%. This was irrespective chain length. Further aging sorbents soil did not cause any release stabilized...
The development of efficient defluorination technology is an important issue because the kind emerging pollutant hexafluoropropylene oxide dimer acid (GenX) as alternative to perfluorooctanoic (PFOA) has higher environmental risks. In UV/bisulfite system, we first developed a hydrophobic confined α-Fe2O3 nanoparticle layer rich in oxygen vacancies, which accelerated enrichment HSO3– and GenX on surface pores through electrostatic attraction interaction, retaining more hydrated electrons...
To investigate whether hydrothermal liquefaction (HTL) could degrade perfluoroalkyl acids (PFAAs) accumulated in plant biomass, we first evaluated degradation of individual and mixed PFAAs pure aqueous solutions. It was found that all five perfluorocarboxylic (PFCAs) were removed completely after 2 h at 300 °C. Three perfluorosulfonic (PFSAs) had removal efficiencies less than 20%. With the amendment KOH, however, PFSAs by HTL increased significantly to 85.9 ± 1.2%. also common cattails...
Recycling of valuable metals from spent lithium-ion batteries (LIBs) is paramount importance for the sustainable development consumer electronics and electric vehicles. This study comparatively investigated two eco-friendly leaching methods recovering Li, Ni, Co, Mn waste NCM523 (LiNi0.5Co0.2Mn0.3O2) cathode materials in LIBs, i.e., chemical by a green organic solvent, levulinic acid (LA) bioleaching an enriched microbial consortium. In leaching, mathematical models predicting efficiency...
