Vg. Torgov et al., Extraction preconcentration of osmium with alpha-olefins followed by radioactivation determination in copper-nickel products, J ANALYT CH, 54(10), 1999, pp. 935-940
An efficient procedure was proposed for the separation of radiochemically p
ure osmium using a new extractant system, alpha-olefins in the presence of
organic sulfides. With the use of this procedure, a unified method of neutr
on activation analysis with improved performance characteristics was develo
ped for determining osmium in products of copper-nickel industry in the con
centration range 0.001-3 g/t.
