A novel method for the separation of halogenated anion complexes of platinum metals by reversed-phase ion-pair partition chromatography has been developed. The separation of RhBr_5^<2->, PdBr_4^<2->,and PtBr_6^<2-> was accomplished on a Hitachi #3050 packed column (3mm×30cm), where 30 % (v/v) acetonitrile-0.02 M phosphate buffer (pH 7) mixture containing 0.1 M tetrabutylammonium bromide and 0.025 M sodium bromide was used as a mobile phase. These anion complexes can be determined at 310nm, and as low as 5×10^<-11> mol of PtBr_6^<-2> can be determined with the peak height method which gave a straight calibration curve. Detecting wavelengths and retention times of the complexes can be altered if the complexes are formed with other halogen ions. This analytical method for micro amounts of platinum metals can remove the mutual metal interferences.
