| Abstract | ||
| Abstract 5-[phenyl azo ]-4,6-dihydrexoy-2-mercapto pyrimidin.(PDMP)has been used for the determination of palladium (П) at trace levels .The inner complex of pd (II) with PDMP at acidic pH , is soluble in aqueous solutions .The complex has a maximum absorption at 572 nm and εmax of 0.76 x 104 L. mol-1.cm-1 . A linear correlation (0.1-5 μg/ml) was found between absorbance at λmax and concentration .The accuracy and reproducibility of the determination method for various known amounts of palladium(П) were tested .The results obtained are both precise (RSD was better than 0.60%) and accurate (relative error was better than 0.55%).The effect of diverse ions on the determination of palladium(П) to investigate the selectivity of the method were also studied .The stability constant of the product under optimized conditions and at room temperature was 1.25x108 L. mol-1. | ||
