Development of a solvent extraction system with 4-heptylaminopyridine for the selective separation of palladium(II) from synthetic mixtures, catalysts and water samples
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.
2-Octylaminopyridine assisted solvent extraction for selective separation and quantification of palladium(ii) ion-pair complexes from synthetic/real samples is developed.
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.
