AB  - A series of Sr-doped BiFeO(3) perovskites (Bi(1-x)Sr(x)FeO(3), BSFO) fabricated 
      via sol-gel method was applied as peroxydisulfate (PDS) activator for 
      ciprofloxacin (CIP) degradation. Various technologies were used to characterize 
      the morphology and physicochemical features of prepared BSFO samples and the 
      results indicated that Sr was successfully inserted into the perovskites lattice. 
      The catalytic performance of BiFeO(3) was significantly boosted by strontium 
      doping. Specifically, Bi(0.9)Sr(0.1)FeO(3) (0.1BSFO) exhibited the highest 
      catalytic performance for PDS activation to remove CIP, where 95% of CIP 
      (10 mg/L) could be degraded with the addition of 1 g/L 0.1BSFO and 1 mmol/L PDS 
      within 60 min. Moreover, 0.1BSFO displayed high reusability and stability with 
      lower metal leaching. Weak acidic condition was preferred to neutral and alkaline 
      conditions in 0.1BSFO/PDS system. The boosted catalytic performance can be 
      interpreted as the lower oxidation state of Fe and the existence of affluent 
      oxygen vacancies generated by Sr doping, that induced the formation of singlet 
      oxygen ((1)O(2)) which was confirmed as the dominant reactive species by radical 
      scavenging studies and electron spin resonance (ESR) tests. The catalytic 
      oxidation mechanism related to major (1)O(2) and minor free radicals was 
      proposed. Current study opens a new avenue to develop effective A-site modified 
      perovskite and expands their application for PDS activation in wastewater 
      remediation.
