Abstract

In this work, a basic study for extraction of palladium (Pd) from the chloride solution by a TBP-kerosene extractant was carried out. Based on thermodynamic Data of species in the Cl–Pd system, and complexes can be stable in low and high concentration of Cl-, respectively. The palladium recovery decreases with the increase in concentrations of hydrochloric acid and chloride salts (NaCl) in the aqueous. The affinity of TBP for Pd extraction changes with chloride species changing. Extraction affinity is higher than as extraction percent 58% and 8% at 0.25 mol/l TBP, respectively. By the use of slope analysis method the organometallic complex of palladium and TBP, formed in the organic phase, was proposed as. whereas couldn' t be extracted from aqueous media.
