In recent years, taking medicine has been increasing around the world due to population growth and the spread of disease. Antibiotics as a kind of these medicines include about 10 to 15% of drug consumption. Studies show that antibiotics, which are not completely removed, have a permanent and destructive effect on the environment. In this study, the chitosan@polyacrylamide@ZIF-8 as an adsorbent was simultaneously used to remove cefixime and amoxicillin from the aqueous solution by adsorption methods. XRD and FTIR patterns were analyzed to investigate the surface crystallinity and the chemical properties of the adsorbent. In the following, SEM and TEM images were used for surface morphology study. Finally, a numerical investigation was done for predicting the adsorption effective par... |
A nanocomposite photocatalyst consisting of titanium dioxide (TiO2) supported on multiwalled carbon nanotubes (MWCNTs) has been successfully prepared and used for the treatment of wastewater contaminated with tetracycline (TC), a recalcitrant antibiotic pollutant. The TiO2/MCNT composites were prepared by a simple evaporation-drying method. The properties of MWCNT/TiO2 were optimized by dispersing different amounts of TiO2 onto MWCNT. The structural and optical characteristics of the nano-engineered photocatalyst composite were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) techniques. Photocatalytic degradation of TC was conducted in a quartz glass reactor. |
