Biological evaluation of a novel in-situ polymerised polyaniline cerium vanadate nanocomposite and its application in environmental remediation.

In the present work, a novel polyaniline cerium vanadate nanocomposite was facilely prepared by in-situ polymerized sol-gel process. X-ray diffraction (XRD) pattern revealed the crystal planes and size of the synthesized nanocomposite. The morphological shape and the crystalline nature of the nanocomposite were examined by field emission scanning electron microscopy (FESEM). Fourier transform infrared spectroscopy (FT-IR) confirmed the conceivable stretching frequency on the surface of nanocomposite. Polyaniline cerium vanadate nanocomposite was used as a solid phase adsorbent for removing methylene blue (MB) from aqueous media. Besides, these nanocomposites evinced antimicrobial activity against E.coli and Staphylococcus aureus. The studies describing the synthesis of polyaniline cerium vanadate by simple in-situ polymerised sol-gel method followed by the investigation of adsorption and antibacterial activities may be useful for the research activities to open a new horizon in the field of nanotechnology.
