Cocatalytic effects of silver and iron photodeposition onto the surface of iso-type homojunction bismuth vanadate for enhancement of solar driven degradation of ciprofloxacin

To further improve photocatalytic degradation of ciprofloxacin (CIP) with iso-type homojunction bismuth vanadate, silver and iron nanoparticles were photodepostied on the surface of photocatalyst. To determine the best conditions and the best photocatalysts for CIP degradation Response surface methodology was used. For iron photodeposited photocatalyst 3 factors [pH (4, 6, 8), concentration of H2O2 in comparison to CIP concentration (5, 17, 5, 30) and mass ration m (FeCl3 x 6xH2O) /m (BiVO4) (5%, 27, 5%, 50%)] were used and for silver ones two factors [pH (4, 6, 8), and mass ration m (AgNO3) /m (BiVO4) (1%, 8%, 15%)] were used, and in both cases the response was degradation of CIP.
