A new solid phase extraction method for the separation and preconcentration of Pd(II) was developed. As solid phase material, a new chelating polymer, poly [N-(4-bromophenyl)-2-methacrylamide-co-2-acrylamido-2-methyl-1-propanesulfonic acid - co-divinylbenzene] was synthesized. The parameters such as the effect of pH, eluent type, volume and concentration, flow rate of sample solution, sample volume and effect of interfering ions for the preconcentration of Pd(II) were investigated. The optimum pH was found to be 9. Eluent for quantitative elution was 10 mL of 1 mol L(-1) HCl. The preconcentration factor of the method was 75. At optimum conditions, the recovery for Pd(II) was found to be 101 +/- 4%. The limit of detection (3 sigma) was 1.1 A mu g L(-1). The method was applied to the determination of palladium in tap water and converter samples with satisfactory results.
