Dependence of the ESR spectra intesity of POBN : O2 adduct on the concentrtions components in non-fenton reaction

In the paper the trapping of the O2 radical by the nitrone a-(4-pyridyl1-oxide)-N-tert-butylnitrone (POBN) compound was investigated. The O2 radicals were generated by the nonFenton reaction of water solutions of KOH and H2O2 reagents. The ESR spectrum of POBN : O2 adduct can be recorded under carefully selected concentration of components. The best spectra were obtained for 6% KOH and 6% H2O2.

W pracy badano pułapkowanie rodnika O2 przez a-(4-pyridyl-1-oxide)-N-tert-butylnitrone (POBN). Rodnik O2 generowano w reakcji niefentonowskiej z KOH i H2O2. Widmo ESR adduktu POBN : O2 powstaje po starannym dobraniu stężeń substratów. Najlepsze widmo otrzymuje się dla stężeń 6% KOH i 6% H202.
