reactions of peroxides
- Main interests in
hydrogen peroxide (H2O2) and peracetic acid (C2H4O3)
- Methods: EPR (spin
trapping), UV/VIS, IR, dissolved O2 electrode, Raman
- Decomposition reaction
mechanisms, kinetics and stabilization
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.
