摘　　要：The equilibrium molalities of In3+ in extraction reaction: In3+(aq)+3HOx(org) = In(Ox)_3(org) + 3H+(aq) were measured at ionic strengths from 0.13 to 2.54 mol-kg~ (-1) in the aqueous phase containing Na2SO4 as the supporting electrolyte and at constant initial molality of extractant, HOx, in the organic phase at temperatures from 278.15 to 308.15 K, where HOx and Ox mean 8-hydroxy-quinoliue and its anion, respectively. The standard extraction constants K0 at various temperatures were obtained by two methods proposed in our previous paper.The equilibrium molalities of In3+ in extraction reaction: In3+(aq)+3HOx(org) = In(Ox)_3(org) + 3H+(aq) were measured at ionic strengths from 0.13 to 2.54 mol-kg~ (-1) in the aqueous phase containing Na2SO4 as the supporting electrolyte and at constant initial molality of extractant, HOx, in the organic phase at temperatures from 278.15 to 308.15 K, where HOx and Ox mean 8-hydroxy-quinoliue and its anion, respectively.
