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 (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 2.21010 dm3mol‒1s‒1 and 1.71010 dm3mol‒1s‒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.
