Abstract
Solubility in the ammonium sulfate (chloride, nitrate)–potassium bis(alkylpolyoxyethylene)-phosphate (oxyphos B)–water pseudo three-component systems has been studied over wide temperature range. The salting-out activity of the ammonium salts towards oxyphos B has been compared, and the possibility of micellar extraction in the studied systems has been demonstrated. Using the ammonium chloride–oxyphos B–water system as an example, extraction of a series of metal ions at 75°С has been performed and compared with the gel-extraction in the ammonium sulfate–oxyphos B–water system at 25°С. It has been found that heating leads to the separation at lower concentration of the components and accelerates the system equilibration.
