Platinum-190 decays to 186Os by emission of an a-particle. Both are platinum-group elements and thus the system has potential use for iron meteorites and PGE-bearing mineral deposits. Walker et al. (1997) determined the decay constant of 190Pt (X =(1.542 0.015) x 10 12 yr half-life =4.5 x 1011 years) and established parameters for... [Pg.277]

There are characteristic chemical properties of cosmic dust that have been involved in the study of sediment accumulation rates. The platinum group elements, such as iridium and osmium, offer good examples. Attempts to use iridium in this way have had the important result of indicating a giant meteorite impact at the Cretaceous-Tertiary boundary (Alvarez et ai, 1980) but it has not been proven important in determining chronometry. [Pg.3179]

Other inorganic reagents utilized in spectrophotometric methods are hydrogen peroxide (see determination of Ti, V, U, and Ce), SnCU ion (determination of platinum group elements [136]), iodide (see determination of Sb, Bi, and Pd), bromide (determination of Au), and also chloride and azide. [Pg.70]

Pd and Rh affect the determination of Pt. The smaller effect of other platinum group elements is due to the lower rate of formation of their complexes with SnCl.. A convenient method of separating Pt from Pd consists in extraction of Pt with triphenylphosphine oxide solution in 1,2-dichloroethane [7] (see the procedure below). [Pg.336]
