Abstract
The kinetics of Pd(II) chloride complex ion recovery from diluted aqueous solutions was investigated using commercially available activated carbon. For this purpose, several different parameters as the influence of temperature, mixing rate, amount of activated carbon applied as well as initial concentrations of Pd(II) chloride complex ions were analyzed. The obtained results showed that the rate of the process is controlled by the mass transfer from the solution to the surface of AC. Therefore, a significant impact of the mixing rate was observed. The activation energy of each step was determined and it is found to be 23.5 +/- 1.3, 52.7 +/- 5.5 and 22.8 +/- 9.5 kJ/mol for adsorption, desorption and reaction of Pd(II) chloride complex transformation. It was shown that commercially available activated carbon, initially designed for gas purification, can be also used for metal ions removal during water purification as well as for precious metal recovery.
