Research


This research concentrates on metal ion catalyzed decomposition reactions of various peroxides and testing of stabilizing agents. Mainly optical (UV/VIS absorption, IR and Raman) and EPR methods are used to identify reaction intermediates and products, and to study their kinetics. These systems often exhibit oscillatory kinetics as well as autocatalysis and hence they provide imporant model systems for chemical kinetics. Furthermore, the results obtained from this research have typically direct industrial applications.
