Golovanova, N. V.Several substances are used for example 24598-62-7 and 7440-04-2 which are their cas registry numbers.; Runov, V. K.; Sadvakasova, S. K.; Khvostova, V. P. (M. V. Lomonosov Moscow State Univ., Moscow, USSR). Zh. Anal. Khim., 46(12), 2336-41 (Russian) 1991. CODEN: ZAKHA8. ISSN: 0044-4502. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Luminescence methods have been developed for detn. of Ru and Os with 1,10-phenanthroline in solns. with relative detection limits of 1 ′ 10-5 and 1 ′ 10-3 mg/mL, resp. Sorption-luminescence methods have also been developed with abs. detection limits of 2 ′ 10-2 and 8 ′ 10-2 mg. An anal. scheme is described which enables the detn. of 10-7-10-6% Ru and Os in 5-10 g samples of ores and rocks. .
