Non-Targeted Analysis Flag: Yes
Non-Targeted Analysis Details: Includes identification, but not quantitation, of degradation products present in solid phase residuals (Figure 6)
Notes: Results include removal efficiency for GenX, ADONA, and F-53B by hydrothermal liquifaction of pure aqueous solutions and cattail biomass
