The Fenton reaction is of significant interest due to its applications in chemical, biochemical, and biomedical studies. It allows the assessment of hydroperoxide content in a sample. For such studies, it is necessary to know the reaction characteristics at different ratios of hydroperoxide and ferrous ion concentrations. The reaction yield is determined by measuring chemiluminescence. This work calculates the number of oxidation acts N(Fe → Fe) in the Fenton reaction for the cases Fe HO and Fe HO with Fe and HO concentrations in the range 10 to 10 mol/L. It is shown that the hydroperoxide concentration can only be unambiguously determined when Fe HO. In the case Fe HO, the strong decrease in reaction rate makes it difficult to register the full chemiluminescence output. The kinetics of the formation of luminescent products in the Fenton reaction were also calculated after the addition of luminol, which enhances the light emission.
