A highly selective, rapid and sensitive spectrophotometric method for determination of pd (II) is Proposed in the acidic media, pd (II) forms a complex with TAN which is soluble in aqueous sodium dodecyle sulfat (SDS) as a micellizing agent and can be monitored spectrophotometrically at 724 nm. The linear range of calibration and detection limit are 0.1-6.0 and 0.0237μgml-1of pd(II), respectively. The result showed that many ions did not interfere with pd (II). The relative standard deviations for 6 determinations of 0.40, 3 and 5.0 palladium are 4.69, 1.32 and 1.63, respectively. The capability of the method for the analysis of real sample was evaluated by determination of pd (II) in tap water sample.
