Abstract

Language:

In this paper, the solvent extraction of platinum(IV) from ascorbate media (0.007 M) has been studied by equilibrating aqueous phase having 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. The extracted metal from organic phase was separated by stripping with water solution (2 X 10 mL). The effect of various parameters, such as pH, extractant concentration, weak acid concentration, equilibrium time, stripping agents, aqueous to organic volume ratio and diluents on the extraction of platinum(IV) was investigated. The extracted species has been evaluated from log D vs log C and species appears to be 1:3:1 (metal:acid:extractant). The selectivity of the method was checked by separating platinum(IV) from binary and ternary mixtures of associated metal ions as well as platinum group metals (PGMs). The extraction separation of platinum(IV) has been achieved from catalysts, anticancer injection, Pt(Rh thermocouple wire and water samples.
