Resumen

Using a green synthesis approach, we have synthesized SnO2 nanoparticles. The morphology of the nanoparticles are characterise by scanning electron microscopy. The UV-vis spectroscopy technique was used to study the optical characteristics. The different parameters such as dosage of catalyst, initial concentration of drugs, effect of pH and other parameters were estimated. The Visible light was irradiated over sample solution at different pH values, and the photo-catalytic effect of the SnO2 nano-particle was observed for degradation of ciprofloxacin drugs. The absorption spectra showed a stronger absorption peak at 273 nm representing the ciprofloxacin drugs. The photo-generated electron of nano-particles degradation drugs, which shows decrease absorption intensity. The results revealed that the photo-catalytic degradation process works well at pH 7. The higher degradation efficiency was observed by following the pseudo-first-order kinetics.
