Bacteria inactivation using spinel cobalt ferrite catalyst

The E. coli inactivation using hydrogen peroxide (H2O2) and cobalt ferrite granulated catalyst was investigated in a fixed-bed flow reactor. CoFe2O4 synthesized by the co-precipitation method, granulated, annealed at 1150°C. X-ray diffraction analysis used to identify crystal structure of catalyst. demonstrates good catalytic activity for bacteria presence H2O2. An increase concentration increases efficiency. reactor 99.94% H2O2 15 mM initial bacterial 6·103 CFU/L. water disinfection broad prospects industrial use.
