Abstract

Pt<sup>II,IV</sup>, Pd<sup>II</sup>, and Au<sup>III </sup>can be separated and quantitated by HPLC in the form of ion-associates of their bromo complexes with the cetyltrimethylammonium (CTMA) cation, using the acetonitrile-water 60 : 40 system containing 0.002 mol l<sup>-1</sup> CTMA and 0.05 mol l<sup>-1</sup> NaBr (pH 3) as the mobile phase and detection at 240 nm. In such circumstances the detection limits for the injection of 20 μl sample are 6.7, 0.4, 0.9, and 4.3 ng for Pt<sup>II</sup>, Pt<sup>IV</sup>, Pd<sup>II</sup>, and Au<sup>III</sup>, respectively. Excess Fe<sup>3+</sup>, Al<sup>3+</sup>, Mg<sup>2+</sup>, Ca<sup>2+</sup>, NO<sub>3</sub><sup>-</sup>, SO<sub>4</sub><sup>2-</sup>, and Cl<sup>-</sup> does not interfere. On-line preconcentration of the Pt<sup>II,IV </sup>bromo complexes on Separon SGX RPS is recommended.
