4DescriptionAbstract A new chromogenic reagent for the sensitive and selective determination of Pd2+ ions in aqueous solution was synthesized. The reagent, 5,6-diphenyl-2,3-dihydro-1,2,4-triazine-3-thione, forms colored complexes with a few heavy metal ions. A 1:1 (M:L) yellowish orange colored complex of DPhDTT-Pd was formed in methanol. The molar absorptivity is 6.67×103 L mol-1 cm-1. Bee’s law was obeyed in the concentration range of 10-50 μg/mL at λmax 385 nm. The accuracy and precision of the method were evaluated on within-day and between-day basis; the relative error was = 3.13 and the relative standard deviation was =3.96. The method was successfully applied to the synthetic samples and results compared with atomic absorption method. There was no significant difference between two methods (p>0.05).
