dc.description.abstractThe present study aimed to modify the surface of polyacrylamide cryogels (PAC) with ZnO nanorods (ZNR) to provide them with antibacterial properties. The synthesized ZNR-modified composite PAC (ZMC) characterized by AAS, FTIR, SEM, XRD, XPS, BET surface analysis and TGA studies. A study of the adsorption of Orange G (OG) and antibacterial effect was performed on the synthesized ZMC. The highest adsorption capacity was determined to be at a dye concentration of 142.79 mg/g at 400 ppm, and a pH of 2. From the data obtained, it was found that adsorption fitted the pseudo-second-order kinetic model and Freundlich isotherm. Modified cryogels could be desorbed in a very short time-such as 30 min-and reused approximately twenty times with 80% efficiency. While ZMC cryogels did not show antibacterial activity in the dark, inhibition percentages were determined as 99.79 +/- 3.94% and 99.81 +/- 1.76%, at 1.78 mg/mL cryogel application, MIC90 values were determined as 1.589 +/- 0.063 and 0.660 +/- 0.028 mg/ mL for Escherichia coli, and Staphylococcus aureus, respectively under visible light. The results showed that the composite cryogels obtained had a very high potential to be applied both in the removal of dyes from wastewater and in the purification of microorganism-contaminated water.
