<abstract xmlns="http://www.w3.org/1999/xhtml">A simple method for the determination of Pd2+-ions using the azo dye 1-(5-benzylthiazol-2-yl)azonaphthalen-2-ol (or BnTAN) and toluene or chloroform as extraction media is proposed. The palladium(II) ion interacts with 1-(5-benzylthiazol-2-yl)azonaphthalen-2-ol creating a chelate complex. This compound was extracted into toluene and chloroform from the alkaline and acid aqueous solutions respectively. Obtained extracts showed absorbance maxima at 600 and 684 nm. Obedience to Beer’s law was established in the range of 0.261 to 0.850 μg mL−1 of Pd(II) and the molar absorptivity of the complex of 6.70 · 103 L mol−1 cm−1 was determined. Optimum reaction conditions for complexation, the effect of variables like time of heating and pH were studied. Detailed studies to check the Pd2+ : BnTAN – stoichiometric ratio were carried out.
