Abstract:A model is developed to describe the degradation kinetics of an organic substance with chaotic structure of macromolecules. The model is based on the results of analysis of lignin structure and its degradation mechanisms described in previous papers of this series. Model postulates are formulated and their chemical substantiation is given. Degradation regimes corresponding to different molecular size distributions are studied. The decrease in organic carbon concentration at the asymptotic stage of the process is shown to obey the power law. Theoretical results were checked against some empirical data taken from the literature.
