Abstract
The effect of NaF and CH3CN on the chemiluminescent reactions of Mn(III) reduction in solutions of sulfuric acid is studied. It is established that NaF is an inhibitor of these reactions, and the quenching of chemiluminescence under the effect of NaF is nominal. Acetonitrile does not affect the kinetics of reactions under similar conditions and acts as a specific quencher of the chemiexcited emitter. The Stern-Volmer quenching constant is 52 ± 11 M−1.
