Discovered by J. A. Sinadecki at University of Vilno,
Poland. Rediscovered in 1828 by G. W. Osann at University of Tartu,
Russia.
Remarks
Lustrous, silvery metal of the platinum group. Unaffected by
air, water and acids but dissolves in molten alkali. Used to harden Pt and
Pd, and as a catalyst.
Diagnostic tests:
There are no simple chemical tests for ruthenium. The element is usually
found as an alloy or a sulfide mineral with other platinum group metals. Atomic Absorption
Spectroscopy is used for quantitative analysis and Energy Dispersive
Analysis of X-rays (EDAX) is used for qualitative analysis.
