Beschreibung

General description

Sodium peroxide (Sodium superoxide) has been synthesized by the matrix reaction of sodium atoms and oxygen molecules at high dilution in argon. Its IR spectral studies have been reported.

Application

Sodium peroxide may be used for the isotope dilution inductively coupled plasma mass spectrometric quantification of Ru, Pd, Ir, Pt and rare earth elements (such as Y, Th, Zr, Hf, Nb and Ta) in various geological samples.
