Efficient Generation of Chemiluminescence during the reduction of manganese(IV) ions with lactic acid

Resumo

The kinetics and mechanism of chemiluminescence during the reduction of manganese(IV) ions with lactic acid in an H₂SO₄–AcOH medium are studied. Kinetic spectrophotometric measurements are used to determine the profiles of change in the concentrations of Mn(IV) and Mn(III) ions during the reaction. The results from kinetic spectrophotometric measurements are compared to the light yield kinetics. The quantum chemiluminescence and chemiexcitation yields reach record values.
