文摘
Equilibrium molalities of ReO4鈥?/sup> were measured in the aqueous phase over the temperature range from (278.15 to 303.15) K, with NH4Cl as a supporting electrolyte at ionic strengths from (0.1 to 2.0) mol路kg鈥?. The standard extraction equilibrium constants K0 at various temperatures were obtained by Pitzer's polynomial approximation method. Thermodynamic properties for the extraction process were also calculated.
