Synergistic strippants of Pd (II) ions in the presence of chloride medium from wastewater of electroless plating process via solvating system: Kinetics and thermodynamics study

Synergistic strippants of palladium complex with Trialkylmethylammonium chloride (Aliquat 336) has been investigated. Results show that synergistic strippants of thiourea and HCl can enhance the palladium stripping efficiency from the loaded Aliquat 336. Extraction of Pd (II) ions is sensitive to the concentration of extractant and chloride medium. The partition coefficient ascertained from the model was fitted with an experimental value. Thermodynamics analysis showed that ?H and ?S values were obtained at 10.74?kJ/mol and 77.81?J/molK, respectively.
