A method is described for the dissolution of platinum metals using potassium pyrosulfate containing potassium chloride. The oxidizing strength of fused potassium pyrosulfate increases with increasing temperature, and at 600 deg C chloride ion appears to be oxidized slowly to chlorine. When the platinum metals are fused with a mixture of potassium chloride and pyrosulfate, they dissolve rapidly. Presumably the chlorine formed acts on the metals directly and the presence of chloride ion removes and stabilizes the products as chloride complexes. Advantages of the method are given. (P.C.H.)
