Abstract: | Quasi-harmonic oscillations of chemiluminescence intensity at certain concentrations of the components for the (S–Cr2O72––UO22+) system in concentrated sulfuric acid and chemiluminescence and dark stages with the participation of intermediates Cr(V), U(IV) and sulfur peroxide radicals (HS2O6.) have been discovered. Chemiluminescence is attributed to the interaction of HS2O6. compounds. The processes of deactivation of the excited states of uranyl involve the participation of Cr(V). A scheme for the oscillation chemiluminescence reactions is suggested.
