ABS>Zirconium is completely precipitated by benzoylphenylhydroxylamine from 0.5N acid solutions. The complex formed in sulfuric acid solutions has a constant composition, Zr(C/sub 13/H/sub 10/0/sub 2/N)/sub 4/, and is used for the direct weighin g of zirconium; the factor is 0.0970. The product precipitated from hydrochloric acid solutions must be ignited to the oxide. The reaction is sensitive, 1 ppm of zirconium being detectable, and quantitative determination of 0.2 mg is possible. Thorium and the rare earths do not interfere. (auth)
