Magnetic Nanoparticles Obtained by Homogeneous Coprecipitation Sonochemically Assisted

Abstract

The present work demonstrates preparation of magnetic nanoparticles by a novel method. Magnetic nanoparticles with potential for biomedical and environmental applications were obtained by homogeneous coprecipitation method sonochemically assisted. The effect of ultrasonic cavitation on changing the reaction environment was studied. The chemical reaction media used here was very similar to those used for Sono-Fenton process. The ultrasonic energy has driven the growth of particles; smaller diameter nanoparticles were obtained by applying a higher power. For the first time, it was demonstrated the iron oxide nanoparticles synthesis at pH lower than 6.

Al and PEG Effect on Structural and Physicochemical Properties of CoFe2O4

“…[10][11][12][13] There are different methods which have been reported for the preparation of magnetic nanoparticles of cobalt ferrite. [14][15][16][17] Cobalt ferrite is a partially inverse spinel with formula (Co x Fe 1-x )[Co 1-x Fe 1+x ]O 4 , formed by oxygen atoms in a closed packing structure where, Co 2+ and Fe 3+ occupy either tetrahedral or octahedral sites. [18][19][20][21][22] Several researchers have reported on Ti, Y, Gd, Pr, Zn, Ni and Dy doped cobalt ferrite.…”

A Comprehensive Review of Magnetic Nanomaterials Modern Day Theranostics

“…Recently, monodispersed magnetic iron oxide nanoparticles of variable sizes have been reported by the use of the stabilizing agent polyvinylalcohols in chainlike clusters signifying the importance of appropriate surfactant for stability (Freitas et al, 2015). Organic stabilizing agents containing carboxylate and hydroxide anions have been the priority choices as they form surface complexes by competing mechanisms (Lu et al, 2007).…”

Magnetite Nanoparticles: Synthesis and Applications in Optics and Nanophotonics

“…De Freitasa et al [ 67 ] demonstrated that the preparation of MNPs using the sonochemically assisted homogeneous co-precipitation method resulted in nanoparticles with sizes of ~35 nm. The authors concluded that the smaller diameter nanoparticles were obtained by applying a higher power and demonstrated iron oxide nanoparticle synthesis at a pH lower than 6 for the first time.…”
