Abstract

Zinc strontium ferrite composites with different ratios (0.95:0.05 and 0.5:0.5) of zinc ferrite and strontium ferrite were synthesized by the co-precipitation technique. Polyvinyl alcohol was used as a surfactant. The formation of polycrystals of zinc strontium ferrite composites was confirmed via X-ray diffraction studies. The crystallite sizes of the sample, determined by Scherrer’s equation was found to be in nanoscale. The antimicrobial activity of the synthesized sample in screening two gram-negative bacteria, two grampositive bacteria, and two fungi was analyzed using the Kirby-Bauer test.
