For the rapid determination of zirconium in magnesium alloys a colorimetric method based on color formation between zirconium salts and morin can be used. The time needed for a simple determination is about 1 hr, but this can be reduced in routine analysis. The reaction between zirconium and morin is not affected by large quantities of Mg, Zn, Ce, Fe, Ni, Co, Cr, Mn, chloride, perchlorate, or sulphate. For Ti a correction curve can be constructed. Fluoride interferes with the color development. Investigation of the reactivity of zirconium metal and actual experience indicate that the soluble and the insoluble zirconium in magnesium alloys cannot be separated by simple dissolution of the base metal in HCl or H/sub 2/SO/sub 4/. Finely divided zirconium is dissolved to a considerable extent by these acids. (auth)
