Electron Paramagnetic Resonance (EPR) spectroscopy and the spin trapping technique were
employed in order to monitor the superoxide radical liberated from potassium superoxide in aqueous alkaline
solutions; DEPMPO (5-diethoxyphosphoryl-5-methyl- 1-pyrroline-N-oxide) was used as a trapping agent. Three
reaction systems were prepared, varying the ratios between KO2, superoxide and DEPMPO. The data indicate
distinct mechanisms leading to DEPMPO/spin adducts with different kinetic rates.
