Abstract: Thin-layer chromatography of the noble metal elements on the inorganic ion exchanger stannic selenopyrophosphate has been studied systematically. The change regularity of the noble metals elements in the acidity medium,the ammonia-ammonium chloride, the trimethylamine and the trimethylamine-alcohol development systems has been discussed. Partial metal ions obey relationship R_m=Alog C+B. A series of binary and ternary mixtures of the noble metal elements was separated successfully.
