Abstract: A simple, rapid and highly sensitive spectrophotometric determination of palladium (II) by using L-Cystine as complexing agent is described. The reagent forms a 1:2 yellow coloured complex with Pd (II) at pH 4, showed maximum absorbance at 369nm.The Beer’s law obeyed over the concentration range 2.12 to16.9 µgL-1 of palladium (II). The molar absorptivity and sandell’s sensitivity of the coloured complex are found to be.2.69x104L mol-1cm-1 and 7.89x10-4 µg/cm2 respectively. The effect of various diverse ions on the estimation of Pd (II) has been studied. The application of the proposed methods was extended to determine Pd (II) in synthetic alloy samples and in hydrogenation catalyst samples.
