Degradation of ciprofloxacin antibiotic under visible light by BIVO4 photocatlyst

Abstract

In this paper, we have successfully synthesized BiVO4 by co-precipitation method. Results of BiVO4 are synthesized under the support of urea, forming a single-line scheelite structure of BiVO4. The synthesized sample were characterized by X-ray diffraction, scanning electron microscopy, raman and UV-visible diffuse reflectance spectra. In this work, the degradation of Ciprofloxacin (CFX) irradiated under visible light (Lamp LED 60W) by BiVO4. The results of SEM images of BiVO4 show that the crystal structure is granular, nanoparticle size and uneven. The Eg value of BiVO4 is 2,312 Ev. The decrease in CFX concentration at pH=3, concentration of 10 ppm and catalyst dosage of 100 mg is the most optimal condition with photodegradation efficiencies of CFX is 75% after 180 min of irradiation. Material obtained in study can be applied in the decomposition of other antibiotics.
