Thermodynamics Study of Rhenium Solvent Extraction Process from Sulfuric Acid Medium
In the rhenium solvent extraction process, molalities of perrhenate after extraction were measured from 278.15 to 303.15 K at impurity ionic strength from 0.2 to 2.0 mol·kg–1 in aqueous phase. Optimization condition of extraction was determined in this sulfuric acid medium. The standard extraction c...

| Zusammenfassung: | In the rhenium solvent extraction process, molalities of perrhenate after extraction were measured from 278.15 to 303.15 K at impurity ionic strength from 0.2 to 2.0 mol·kg–1 in aqueous phase. Optimization condition of extraction was determined in this sulfuric acid medium. The standard extraction constants K 0 at various temperatures were obtained by method of polynomial approximation. Thermodynamic quantities for the solvent extraction process were calculated. |
