Palladium(II) forms a light yellow 1 : 1 :2 complex with benzildioxime in presence of thiobyanate at 0.10-1.00 mol L^-1 HCI.The complex is non-extractable in nature and shows absorption maximum at 363-368 nm.The molar absorptivity of the complex is 3.088 x 10³ L mol^-1 cm^-1 with a Beer's law range of 0-15.5 μg ml^-1 The method Is quite simple and rapid and has been satisfactorily applied for the determination of palladium in μg amounts in various synthetic and technical samples.
