Synthesis of IONPS by mixing leek extract with iron chloride salt for antibacterial application

Abstract

Synthesis of IONPS by mixing leek extract with iron chloride salt. By simple chemical process, with Change in PH which has a variety of effects on the optical and structural properties of IONPs. The iron oxide NPs were characterized by XRD, SEM and UV–vis techniques. XRD results showed average Crystallite size changed from (23.23) nm to (20.70) nm as pH was increased from 1.6 to 12. The particle size of (a-Fe2O3) NPs was about (101.60) nm in SEM pictures, but as the PH increased, the particle size decreased to(34.30) nm. UV–vis measurements showed energy band increased from ( 3.33-5.62) eV. Antimicrobial activity of iron oxide NPs was determined by growth inhibition zones of the gram negative bacteria E.coli, Klebseilla spp and gram-positive bacteria S.aureus, S.epidermidis and fungal Candida albicans. It found the zones for (a-Fe2O3) NPs when PH 1.6 was between (12-14) mm. The zones for (a-Fe2O3) NPs when PH 12 was between (12-13) mm.
