Application

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

General description

Sodium peroxide (Sodium superoxide) has been synthesized by reacting sodium atoms and oxygen molecules at high dilution in argon. Its IR spectral studies have been reported. It is a strong oxidizing agent.
