Abstract

Molalities of In3+ were measured at ionic strength from 0.1 to 2.0 mol·kg−1 in aqueous phase containing Na2SO4 as supporting electrolyte and at constant molality extractant at temperatures from 278.15 to 303.15 K in organic phase. The standard extraction constants K 0 at various temperatures were obtained by methods of extrapolation and polynomial approximation. Thermodynamic quantities for the extraction process were calculated.
