The reversed-phase HPLC of several platinum group metal complexes with a new chromogenic reagent 4-(5-nitro-2-pyridylazo)resorcinol (5-NO(2)-PAR) on an ODS column using methanol-ethyl acetate-water (50:10:40, v/v/v) containing 10 mM HAc-NaAc buffer (pH 4.0), 10 mM tetrabutylammonium bromide and 10 mM Na(2)EDTA was investigated. The detection wavelength was 536 nm. Pd(II), Rh(III), Ru(III) and Pt(II) complexes of 5-NO(2)-PAR were separated and determined simultaneously within 18 min. Calibration ranges (ng/ml) were 1.5-500 for Pd(II), 1.5-500 for Rh(III), 2.1-500 for Ru(III) and 7.8-500 for Pt(II). Detection limits were 0.5, 0.5, 0.7 and 2.6 ng/ml, respectively.
研究了几种铂族金属配合物与新型显色剂4-(5-硝基-2-吡啶偶氮)间苯二酚(5-NO(2)-PAR)在ODS柱上的反相高效液相色谱，流动相为含10 mM HAc-NaAc缓冲液(pH 4.0)、10 mM四丁基溴化铵和10 mM Na(2)EDTA的甲醇-乙酸乙酯-水(50:10:40, v/v/v)。检测波长为536 nm。5-NO(2)-PAR的Pd(II)、Rh(III)、Ru(III)和Pt(II)配合物在18分钟内可同时分离并测定。校准范围(ng/ml)分别为：Pd(II)为1.5 - 500，Rh(III)为1.5 - 500，Ru(III)为2.1 - 500，Pt(II)为7.8 - 500。检测限分别为0.5、0.5、0.7和2.6 ng/ml。
