Find out more about cationic and zwitterionic PFASs
Cationic and zwitterionic PFASs are subgroups of per- and polyfluoroalkylated substances (PFASs) that differ from the more commonly studied anionic PFASs. Cationic PFASs carry a positive charge, while zwitterionic PFASs have both positive and negative charges.
These compounds are often present in fire-fighting foams (AFFF) and can be found in soil and water contaminated by these foams.(AFFF) and can be found in soils and waters contaminated by these foams. They are less well characterised than anionic PFAS, which makes their quantification and study more complex.
Examples of cationic structures:
- Fluorinated quaternary ammoniums
- Protonated fluorinated alkylamines
Finally, zwitterionic PFAS behave in a particularly complex way in environmental and biological matrices , making their analytical analysis tricky.
