Özet

Synthesis of nanoparticles using surfactant systems such as water-in-oil micro emulsion systems or reverse micellar systems brings perfect particle control over particle size. In this study, reverse micellar system was formed with anionic surfactant AOT in isooctane to produce CoFe2O4, with particle size ranging with 15 - 150 nm. In addition, effects of reaction time, concentration of FeSO4 center dot 7H(2)O and AOT on the nanoparticle formation were investigated. The molar concentration of FeSO4 center dot 7H(2)O was found to be an important parameter in control of nanoparticle size. A decrease in the concentration of FeSO4 center dot 7H(2)O resulted in larger CoFe2O4 particles.
