Trends of salting out of oxyethylated anionic surfactant potassium bis(alkylpolyoxyethylene)phosphate with inorganic salts

Abstract

The effect of salt structure on the ability to salt out oxyphos B from aqueous solutions is elucidated using the solubility data in pseudo-ternary inorganic salt–potassium bis(alkylpolyoxyethylene)phosphate (oxyphos B)–water systems in the temperature range of 20–90°С. The results are interpreted according to the Samoilov’s theory of salting-out.
