Facile fabrication of chitosan-cl-poly(AA)/ZrPO4 nanocomposite for remediation of rhodamine B and antimicrobial activity

Abstract

The chitosan based nanohydrogel reinforced nanocomposite was fabricated by facile sol–gel polymerization technique. A chitosan-cl-poly(AA)/ZrPO4 nanocomposite was discovered as a capable photocatalyst for the elimination of rhodamine dye. The designed chitosan-cl-poly(AA)/ZrPO4 nanocomposite was examined by various characterization approaches such as Scanning electron microscopy (SEM), X-Ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and Transmission electron microscopy (TEM). The photocatalytic experiment outcomes revealed that the nanocomposite had good remediation potential as 82% of rhodamine B dye was remediated within 3 h of process. The antimicrobial behavior of nanocomposite was studied against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus bacteria. Cell toxicity of the synthesized chitosan-cl-poly(AA)/ZrPO4 nanocomposite was performed against Vibrio fischeri as model organism. The chitosan-cl-poly(AA)/ZrPO4 nanocomposite demonstrated the potential antibacterial behavior. Keywords: Nanocomposite, Zirconium Phosphate, Chitosan, Photocatalysis, Antimicrobial
