Abstract: The formation of the red chelates of palladium with 4-(2-pyridylazo)- resorcinol in the presence of the cationogennic tenside cetylpyridinium bromide is used to develop a highly sensitive extraction spectrophotometric method for the determination of Pd(II). The best results (ε540nm = 9.16 x x 104 dm3 mol-1 cm-1 , S = 1.16 x 10-3 (μg Pd(II) cm-2 , determination of mass concentrations to 1.9 μg Pd(II) cm-3 were obtained with extraction of a solution of palladium(II) salt using a chloroform solution of a mixture of PAR—СРВ, where the coloured product is stable for 7 h.
