Zusammenfassung:Perfluoroalkanesulfonamide salts (I) are new. Perfluoroalkanesulfonamide salts of formula (I) are new: RfSO2NH- Y+ (I); Rf = 7-9C perfluoroalkyl; Y = a cation. Independent claims are also included for: (1) a process (P1) for preparing compounds (I); (2) a process (P2) for recovering polyvalent cations from an aqueous solution by adding a compound (I), recovering a complex of formula (II), dissociating the complex by treatment with an acid, separating the sulfonamide RfSO2NH2 and recovering the salt of the polyvalent cation and the anion of the acid; (3) complexes of formula (II). (RfSO2NH-)nM (II); M = a n-valent cation; n = 2 or more.
