Abstract:

A pulse radiolysis study was carried out to investigate the radical anion and radical cation of sparfloxacin (SPAX). The reactions of SPAX with hydrate electron (eaq ?), hydroxyl radical (·OH) and azide radical (·N3 ?) were investigated in this study. The transient absorption spectra of SPAX radical anion and SPAX radical cation were obtained. Two transient rate constants 2.2×1010 dm3·mol?1·s?1 and 1.7×1010 dm3·mol?1·s?1 for the reactions of SPAX with eaq ? and ·OH were determined, respectively. Finally, based on the results obtained in this study, rational mechanisms of transient reactions were proposed.

Key words: Sparfloxacin, Pulse radiolysis, Radical cation, Radical anion
