Description

Isotherm of uranyl nitrate extraction by 100 % di-isoamylmethylphosphonate (dampa) from concentrated water-salt solutions is described with allowance made for formation of uranyl nitrate di- and trisolvates in organic phase. Values of constants of phase extraction equilibrium are determined. Values of excess functions of mixing of dampa and uranyl nitrate disolvate solutions at 298 K are given. 9 refs.; 2 tabs
