| 中文摘要 | the synergistic extraction of rare earths (la, nd, gd, y and yb) with a mixture of 2-ethylhexyl 2-ethylhexylphosphonate (ehehpa) (ha) and trialkylphosphine oxide (cyanex 923) (b) from a hydrochloride medium was investigated. the mixed system significantly enhances the extraction efficiency for lighter lanthanides and the synergistic enhancement coefficients for la (4.52), nd (3.35), gd (2.08), y (1.31) and yb (1.08) decrease with decreasing ionic radius of the rare earths. the extraction equilibrium of la, nd and gd indicate that la and nd were extracted as ma(3)(.)b, whereas gd was extracted as gd(oh)a(2)(ha)(2)b-.. the equilibrium constants, thermodynamic functions such as delta g, delta h and delta s and formation constants of the extracted species were determined. the stripping properties were also studied. |
