The salt impact of five different sodium salts (NaCl, NaBr, NaI, Na2SO4, and Na2HPO4) and four different chlorides (NaCl, KCl, LiCl, NH4Cl) was investigated. The influence of the inorganic additives was studied at 30 °C because at this temperature all prepared mixtures faced a separation above the cloud point temperature (CPT) in micellar (surfactant-rich) and aqueous (surfactant-lean) phase. The salting-out ability of the cations follows the series Na+ > K+ > NH4+ > Li+. We observed a more pronounced effect among the anions, where the salting-out effect decreased in the order HPO42- ≈ SO42- > Cl- > Br- > I-. All salts, except NaI, lead to an increase in the Triton X-114 concentration in the micellar phase and to a decrease of the surfactant fraction in the aqueous phase. Inorganic salts also distributed unevenly between both phases and, thus, accumulated in the aqueous phase. In the case of stronger salting-out kosmotropic anions (HPO42-, SO42-), the salt load of water in the aqueous phase was higher compared to the weaker agents Br- and I-.en1520-5134Journal of chemical & engineering data2016414961501American Chemical SocietyTechnikInfluence of inorganic salts on the phase equilibrium of triton X-114 aqueous two-phase systemsJournal Article10.1021/acs.jced.5b00821Other
