Description 32-39
Chitosan/polyvinyl alcohol (CS/PVA) membranes containing silver nitrate have been prepared and investigated for
antimicrobial properties of prepared membranes. CS/PVA membranes containing silver nitrate have been successfully
prepared by solution casting method. The prepared membranes have been characterized by Fourier transform infrared
spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction analysis (XRD) methods. The elemental
composition of the membranes is studied by energy dispersive analysis of SEM-EDX. Correspondingly, the EDX analysis
confirms the presence of silver ions in the chitosan matrix. The antimicrobial activities of the membranes have been tested
with wide spectrum of bacteria. Efficiency of the antimicrobial effect against the selected twelve bacteria type and two
yeasts is measured by disc diffusion method. Effect of the concentration of silver solutions to the developed CS/PVA
membranes was investigated. It is noticed that the antimicrobial activity of membranes is improved with the increased silver
concentration as a bactericidal agent, as expected. Our observations suggest that Chitosan/polyvinyl alcohol/Ag
(CS/PVA/Ag) membranes have an excellent antimicrobial effect. Thus, developed membranes can easily be applied in
various fields such as biomedical sector, tissue engineering and water treatment sector.
