Kinetic Study of the Complexation of Palladium (II) With 2-(5-Bromo-2-Pyridylazo)-5-Diethylaminophenol
Abstract
The kinetics of the complexation reaction of palladium with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) has been studied in the stability time at the optimum pH of 3.53 in presence of 50% ethanol. The effect of ionic strength and temperature on the reaction rate were reported. A mechanism has been postulated and the stability constants of the individual steps were determined. The Arrhenius and thermodynamic parameters were evaluated and discussed.
