摘要

The equilibrium molalities In³⁺ in {In₂(SO₄)₃+Na₂SO₄+HDEHMTPCA+n-C₈H₁₈+water} were measured at ionic strength from (0.1 to 2.0) mol脗脗kg^脗脗脗1 containing Na₂SO₄ as supporting electrolyte in aqueous phase and at constant molality extractant at temperatures from (278.15 to 303.15) K in organic phase. The standard extraction constants K⁰ at various temperatures were obtained by methods of extrapolation and polynomial approximation. Thermodynamic quantities for the extraction process were calculated.
