An alternative treatment method for fluorosurfactant-containing wastewater by aerosol-mediated separation

Foam fractionation removal of multiple per‐ and polyfluoroalkyl substances from landfill leachate

“…Similar results were reported for spiked leachate by Robey et al (2020), specifically, greater than 90% removal for PFOA, PFOS, PFHxS, and PFHpA, while PFHpS had lower removal efficiency than that of PFOS or PFHxS, and less than 10% removal efficiency for PFBA, PFPeA. Ebersbach et al, 2016 also reported similar results including over 90% removal for 6:2 FTSA.…”

Phase-out-compliant fluorosurfactants: unique methimazolium derivatives including room temperature ionic liquids

“…107 Open issues remain, though, as the cleaved fluorotelomer would require appropriate recycling, but neutral fluorous degradation products are separable from aqueous phases with minimal efforts. [108][109][110] Further details of oxidative conversion pathways will be reported in a forthcoming communication.…”

Global transport of perfluoroalkyl acidsviasea spray aerosol

“…60 As such, it is an essential requirement of any laboratory system that is designed to produce nascent SSAs with relevant physical and chemical characteristics that it reproduces the numbers and sizes of bubbles entrained by breaking waves in the open ocean. 74 Previous studies have demonstrated strong enrichment of PFAAs in laboratory generated aerosols relative to their bulk water concentration 44,45,75 using a number of different methods to produce bubbles. McMurdo et al 45 utilised a piezoelectric crystal ultrasonic aerosol generating device to generate aerosols much larger ($50 mm) than those typically produced over the ocean (<10 mm).…”

“…Furthermore, the production of SSAs is strongly inuenced by seawater salinity. [78][79][80][81] Ebersbach et al 75 generated aerosols from wastewater by entraining air using a diffuser/frit. Experiments using such an approach are non-ideal in that the bubble sizes generated depend on the exact frit used and do not reproduce the bubble size distributions found in oceanic breaking waves.…”
