Antibacterial and Methylene Blue Dye Degradation Activity of hibiscus rosa sinensis Synthesized CoFe 2 O 4 Nanocomposites

Co‐precipitated biotic CoFe 2 O 4 nanoparticles from the leaves of the Hibiscus rosa sinensis plant were used to produce bio‐reductant nanoparticles. The CoFe 2 O 4 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 CoFe 2 O 4 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 CoFe 2 O 4 nanoparticles and the material they were made were present. VSM analysis confirmed the super‐paramagnetic nature of the CoFe 2 O 4 nanoparticles and magnetic pulse. Biosynthetic CoFe 2 O 4 nanoparticles were used to eliminate organic(MB dye) and bacterial(S. aureus, B.Substils, and E. coli bacterial strains) pollutants. Spinel ferrite biosynthetic CoFe 2 O 4 nanoparticles are capable of generating radical superoxide ions.
