Abstract

Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula CnF(2n + 1)SO3H. PFSAs with six or more perfluorinated carbon atoms are referred to as long chain. These chemical compounds belong to the family of per- and polyfluoroalkyl substances, also known as so-called forever chemicals. Reference spectra in both polarities are presented of the potassium salts of one long-chain perfluorosulfonic acid, namely, perfluorooctanesulfonic acid with an eight-carbon fluorocarbon chain, and one short-chain perfluorosulfonic acid, namely, perfluorobutanesulfonic acid with a four-carbon fluorocarbon chain.
