Chemiluminescent reactions in the Belousov-Zhabotinskii oscillating system.

Chemiluminescence (CL) occurs during reactions of several of the components of the CH2 (COOH)2-KBrO3-MnSO4-H2SO4 self-sustained system. In contrast to the kinetics determined using potentiometry and spectrophotometry, the CL intensity kinetic curve during the oxidation of manganese (II) ions by acidic bromate has an extremum. Experimental dependences of the maximum CL intensity value on the initial reagent concentrations have been determined and compared with the results of the numerical simulation based on the commonly accepted Noyes-Field-Thompson mechanism.
