In this paper, the solvent extraction of platinum(iv) from ascorbate media (0.007 M) has been studied by equilibrating the aqueous phase (pH 1.5) with 10 mL of 0.06 M 4-heptylaminopyridine (4-HAP), as a novel anion exchanger, diluted in xylene for 2 min.

Solvent Extraction System

In solvent extraction system of perrhenate with the extractant of N235 at high concentration, the equilibrium molalities of ReO4- were measured at ionic strengths from 0.2 to 2.0 mol.kg-1 in the aqueous phase containing Na2SO4 as the supporting electrolyte from 278.15K to 303.15K. The standard extraction constants K0 at various temperatures were obtained. Thermodynamic quantities for the extraction process were also calculated.

Measured Distribution

A previously determined thermodynamic model for extraction equilibrium is used as a basis to predict experimentally measured distribution coefficients for the CuSO4–H2SO4–LIX 984–Escaid 103 solvent extraction system at 25 °C and aqueous copper concentrations in the range 0.01–2.0 gL−1, the copper loading isotherm is also obtained.
