Evaluation and determination of kinetic and thermodynamic chemiluminescence characteristics of a novel peroxyoxalate system using two new triazine derivative

Authors

Abstract

The chemiluminescence arising from the reaction of bis(2,4,6-trichlorophenyl)oxalate (TCPO) with hydrogen peroxide in the presence of fluorescent brighteners 4,4’-Bis{[4-anilino-6-bis(2-hydroxyethyl)amino-1,3,5-triazin-2-yl]amino} stilbene-2,2’-disulfonic acid- disodium salts (Triaz I), 4,4’-Bis{[4-6-anilino -1,3,5-triazin-2-yl]amino}stilbene-2,2’-disulfonic acid- disodium salts (Triaz II) has been studied. The influence of concentration of Triazinyl, TCPO, hydrogen peroxide, catalysts concentration, catalyst type and temperature on the chemiluminescence was investigated. The kinetic parameters for the peroxyoxalate-chemiluminescence of Triazinyl were appraise from computer fitting of the resulting intensity–time plots. The activation parameters such as Ea and G, were evaluated from temperature dependence of the corresponding fall rate constants.
