Chemiluminescence accompanying chitosane destruction in hydrochloric acid solution containing hydrogen peroxide

Russian Chemical Bulletin Aims and scope

Abstract

The chemiluminescence (CL) accompanies the destruction of chitosane (CTS) in the presence of H2O2. The CL kinetics has a complex character and can be described as a sum of two exponentials. The photoluminescence monitoring and IR spectra of the reaction mixture indicate the formation of carbonyl groups in the course of CTS destruction. The enhancement of the CL intensity by Fe2+ suggests the reaction of Fe2+ with hydroperoxides accumulated with CTS decomposition. The macroradicals ROO· are assumed to be transformed through the cleavage of the glycoside bond via a six-membered cyclic intermediate to form the terminal peroxide radical and ketone.
