Fig. 14: Total PFAS, fluoride concentrations and fluorine mass balance at various reaction temperatures.

From: Technology status to treat PFAS-contaminated water and limiting factors for their effective full-scale application

Fig. 14

a Concentration of PFAS (PFOS, PFHpS and PFCA) intermediates from LC-MS/MS analysis, and the fluoride concentration obtained from ion chromatography, b the quantity of both organic and inorganic fluorine in liquid effluents, c proposed decomposition pathways of PFOS obtained from SWCO using intermediates from GC-MS. Noteworthy: although 1H-perfluorohexane was the only volatile organic fluoride identified other volatile organic fluorides cannot be excluded96.
