摘要

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 (e(aq)(-)), hydroxyl radical ((OH)-O-.) and azide radical (N-.(3)-) were investigated in this study. The transient absorption spectra of SPAX radical anion and SPAX radical cation were obtained. Two transient rate constants 2.2x10(10) dm(3.)mol(-1.)s(-1) and 1.7x10(10) dm(3.)mol(-1.)s(-1) for the reactions of SPAX with e(aq)(-) and (OH)-O-. were determined, respectively. Finally, based on the results obtained in this study, rational mechanisms of transient reactions were proposed.
