Green synthesis of Magnetite Iron Oxide Nanoparticles by Using Al-Abbas's (A.S.) Hund Fruit (Citrus medica) var. Sarcodactylis Swingle Extract and Used in Al-'alqami River Water Treatment

Abstract

In this study, magnetite iron oxide nanoparticles were synthesized from aqueous ferrous chloride, ferric chlorideand sodium hydroxide through a simple and eco-friendly route using Al- Abbas's (A.S.) Hund Fruit extracts,which acted as a reductant and stabilizer simultaneously. Characterizations of nanoparticles were done by usingUV-visible, FT-IR, XRD, and SEM methods. The ultraviolet-visible spectrum of the aqueous solution containingmagnetite iron oxide nanoparticle showed an absorption peak at round 340 nm. FT-IR graph showed peaks at519 cm -1 confirm the presence of Magnetite iron oxide nanoparticles in the synthesized samples. It is clear thatthe bioactive molecules present in the Abbas's (A.S.) Hund Fruit extract interacted with the synthesizedMagnetite iron oxide nanoparticles. The diffractogram exhibits six distinct diffraction peaks at 2θ values, as the(220), (311), (400), (422), (511) and (440) crystallographic planes of the inverse spherical magnetite crystal. Theaverage crystallite size was evaluated by diffraction line broadening (d 311) using the Debye-Scherrer equation.The average size of Fe3O4 crystallites obtained from nanocomposite was about 45nm. The magnetite iron oxidenanoparticles synthesized by the help of Abbas's (A.S.) Hund Fruit extracts were scanned using SEM. It revealsthat an iron oxide nanoparticle seems to be spherical in morphology.The Al-'alqami River water treatment by magnetic iron oxide nanoparticles synthesize by Abbas's (A.S.) HundFruit extracts led to the reduction of the number of bacteria to 80% after twelve hours of treatment whereas watertreatment by magnetic iron oxide nanoparticles for 24 hours led to kill all the bacteria in water.Keywords: Green synthesis, Magnetite Iron Oxide Nanoparticles, Al- Abbas's (A.S.)
