摘要：
The solubility isotherms were constructed for the ternary systems H2O-DS-10 synthanol-(NH4)(2)SO4 and H2O-ALM-10 synthanol-KSCN at 298 K. The regions of two-phase liquid equilibrium were revealed. The interphase distribution of some metal ions was examined. It was established that cobalt(II) and zinc ions were quantitatively extracted into the phase of the surface-active substance in the system with potassium thiocyanate.
