    • Amoxicillin and cefixime simultaneous adsorption by facile synthesized chitosan@polyacrylamide@ZIF-8: isotherm and kinetic study
    Authors: Zadvarzi, Saber Babaee; Amooey, Ali Akbar;  Advisor: -;  Co-Author: - (2023)

    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...
    • Synthesis, electrospinning, and molecular docking of poly(methyl methacrylate) Schiff bases and their applications as polymeric antimicrobial agents and for dye removal
    Authors: Kenawy, El-Refaie; Ghazy, Ahmed R.; Al-Hossainy, Ahmed F.;  Advisor: -;  Co-Author: - (2023)

    The antibacterial activity of a variety of modified poly(methyl methacrylate) Schiff bases against common microbial infections and removal of methylene blue (MB) dye were screened. The Schiff bases were synthesized from the reaction of the modified (PMMA) with vanillin (PMMA)Van and cinnamaldehyde (PMMA)Cin. By using Fourier transformer infrared (FT-IR), X-ray diffraction analysis (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), the structures of the nanofibers of the synthesized Schiff bases were confirmed. The modified Kirky–Bauer method was used to screen the antibacterial activities of all the obtained materials against various bacterial species, including gram-positive bacterial (Bacillus subtilis (4k1p), Staphylococcus aureus), Gram-negative bac...
