Abstract

Abstract: The thermodynamic equilibrium model of acidic phosphoric extractant and metal system was studied with thermodynamic method. The activity coefficients of the components such as water, C₆H₁₄, extractant in organic phase can be calculated according to the thermodynamic relation, and γ_Cu²⁺ can be estimated according to Pitzer's equation. The experimental data can be used to correlate and solved on computer. The results showed that the thermodynamic equilibrium constant Kwas in the range of 1.62×10^～7 ～5.26×10^-7 and the activity coefficients of the components were achieved.

Key words: Extractive equilibrium constant, Activity coefficient, P₅₀₇ extractant
