Antibacterial and Methylene Blue Dye Degradation Activity of hibiscus rosa sinensis Synthesized CoFe2O4 Nanocomposites.

Co‐precipitated biotic CoFe2O4 nanoparticles from the leaves of the Hibiscus rosa sinensis plant were used to produce bio‐reductant nanoparticles. The CoFe2O4 biomolecules were analyzed using EDX analysis to identify their structure through XRD, FTIR, UV, VSM, and SEM characterization. The cubic phase and crystallite size of biotic CoFe2O4 nanoparticles were determined using XRD analysis. The FTIR spectroscopy was used to confirm Cation migration and Co−Fe−O interaction. Using SEM, TEM, and EDX, it was confirmed that spherical biosynthesized CoFe2O4 nanoparticles and the material they were made were present. VSM analysis confirmed the super‐paramagnetic nature of the CoFe2O4 nanoparticles and magnetic pulse. Biosynthetic CoFe2O4 nanoparticles were used to eliminate organic(MB dye) and bacterial(S. aureus, B.Substils, and E. coli bacterial strains) pollutants. Spinel ferrite biosynthetic CoFe2O4 nanoparticles are capable of generating radical superoxide ions. [ABSTRACT FROM AUTHOR]
