Abstract

The reaction of uranium(IV) with O2 in aqueous solutions of HClO4 is accompanied by chemiluminescence (CL). The CL intensity and the reaction kinetics are appreciably affected by introduction of the glass beads with a radius of 1 mm. In the presence of 1600 beads (the surface area of the glass is 200 cm2), the yield of CL dereases 32-fold. The effect of the solid surface on the kinetic and chemiluminescence parameters of the liquid-phase radical chain reaction is due to the increased role of chain termination upon heterogeneous decay of the HO 2 . and.OH radicals.
