OXYGEN STATES IN THE CASE OF INTERACTION OF O-2 WITH METAPHOSPHATE MELTS CONTAINING 3D-METAL IONS

Interaction between atmospheric oxygen, the air-methane mixture and me thane, on the one hand, and NaPO3 melt and binary NaPO3-CoO, NaPO3-Sc2 O3 and NaPO3-ZnO melts, on the other hand, has been studied by electro n absorption (EA), electron spin resonance (ESR) and IR spectroscopy. The formation of different types of superoxide ions has been revealed O-2-; in NaPO3 (g = 2.000) and (O?2 delta radical anion) (g = 1.921 an d 1.924) in the oxygenated [(PO3-)(y)M . O-2(delta radical anion)] com plex (where M = Co2+, Zn2+) with electron density delocalized between ions of the complexing metal and O-2(radical anion).
