摘　　要：纸色谱法使pt(Ⅳ)与其它贵金属分离,Luminol-H_2O_2-SCN^--pt(Ⅳ)化学发光法测定责金属混合试液中的微量pt(Ⅳ)。A sensitive chemiluminescence system of luminol-H_2O_2-SCN_--pt(Ⅳ) has been presented in this paper. The detection limit of pt(Ⅳ) has come down to 0.09 ppm. After Au-Pt-Ru-Rh-Os-Ir mixture is separated by paper chromatography, the method can used in the determinatio n of microamount of platinum(Ⅳ). The recovery is over 96％.
