Abstract
In the paper we proposed to use the delaminating system water – oxyphos B – sodium sulphate for the purposes of extraction. Solubility isotherms have been obtained for the system at 25 °С. Concentration ranges have been established for the region of two-phase liquid equilibrium. An interphase distribution of certain metal ions has been studied at a concentration thereof equal to 1 · 10–4 mol/L in the presence of HCl or H2SO4.
