Sažetak
The presence of antibiotics in the environment may threaten both humans and wildlife because of their resistance and chronic toxicity. Ciprofloxacin (CIP) is one of the antibiotics included in the European Commission's Watch list which should be concerned for removal from groundwaters. Among the various strategies, the solar driven photocatalytic process using semiconducting materials seems to be one of the effective methods to remove antibiotics from aqueous solutions. In this research, a series of transition metal Fe- modified BiVO4 materials were synthesized employing photo-deposition technique using different amounts of iron. The asprepared materials were characterized via FTIR, XRD, SEM, UV-vis DRS and electrochemistry measurements. Photoelectrochemical properties of materials showed that photo-deposited iron (nano)particles are markedly beneficial for reducing e-/h+ recombination in synthetized isotype homojunction BiVO4. The photocatalytic activity of as-prepared materials was examined by monitoring the degradation of ciprofloxacin (CIP) as a model organic pollutant under solar irradiation within different pH range (4 to 8) employing Fe-BiVO4 with different fe content photodeposited (1 to 15%) and compared to that of pristine iso-type homojunction BiVO4.
