Abstract

Manganese-Zinc Ferrite (MnxZn1-xFe2O4) powder was prepared using the "sol-gel" technique. Structure and antibacterial properties of the sample were investigated by XRD, AFM, EDX, and FE-SEM. X-ray diffraction (XRD) determined that MnxZn1-xFe2O4 has a cubic structure. The atomic force microscopy (AFM) determined that the average diameter of Manganese-Zinc Ferrite is (55.35nm), indicating that the sample has a nano-structure dimension. Energy dispersive X-ray (EDX), was conducted to assess the surface morphology and elemental compositions of Manganese-Zinc Ferrite.  FE-SEM was used to look at the shape of the surface. The microphotograph showed that the shape was homogeneously spherical.  Antibacterial properties  results for PVDF, pure MnxZn1-xFe2O4 and PVDF doped different ratio MnxZn1-xFe2O4 and add a constant amount of activated carbon (PVDF: MnxZn1-xFe2O4 /AC) to study  the biological activity for two types of bacteria positive S-aurous and negative E-coil the result showed the nano-ferrite has good activity for both type and the diameter for inhibition zones was ranged (25-17) mm.
