| Abstract |
| Absorption spectra of ruthenium in simple soda silica glasses were determined.
Absorption maximum occurred at 680-690 milli micron in all glasses and at 465 and
510 millimicron in basic and relatively acidic glasses. Absorption spectra of a tetravalent
ruthenium complex in KOH solution was reported. Comparison of absorption spectra
of ruthenium in glass with that of the known spectra of ruthenium in solution indicated
that ruthenium may be present in glass as tri-, tetra- and hexavalent ruthenium depending
on glass composition. |
