Description

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. It is a strong oxidizing agent.

Sodium peroxide is a strong oxidizing and bleaching agent mainly used in bleaching papers and textiles. It is an effective oxidizing flux for the decomposition of minerals and ores.

Application

Sodium peroxide may be used as an oxidant for:
conversion of Δ⁴-3-ketosteroids to Δ⁴-3,6-diones
oxidation of alduronic and glyculosonic acids

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.
