Zirconium is completely precipitated by benzoylphenylhydroxylamine from 0.5 N acid solutions. The complex formed in sulphuric acid solutions has a constant composition, Zr(C13H10O2N)4, and is used for the direct weighing 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 p.p.m. of zirconium being detectable, and quantitative determination of 0.2 mg is possible. Thorium and the rare earths do not interfere.
