Abstract
A simple, rapid, and selective spectrophotometric method is proposed f or the determination of palladium-(II), using 4-(dimethylamino)benzald ehyde thiosemicarbazone (DMABT) as a spectrophotometric reagent. The r eagent forms a 1:2 complex (Pd: Reagent) with Pd(II) in the pH range 2 .2-3.6. The complex is soluble in aqueous solution containing 20% acet one and 30% ethanol by volume. Beer's law is valid upto 2.3 ppm of pal ladium. The molar absorptivity is 4.59x10(4) dm3 mol-1 cm-1 and Sandel l's sensitivity 2.33x10(-3) mug cm-2. The method tolerates large numbe r of cations and anions.
