Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The 23 full-factorial Central Composite Design (CCD) and response surface methodology (RSM) was applied to explain the effect and interaction of three factors in the process of Fe3O4/SiO2 nanoparticle: NaOH dosage, Fe3O4/SiO2 ratio and Fe2+/Fe3+ ratio. For the CCD optimization purposes, the canonical parameters was employed where the predicted average size of the nanoparticles was 115.39 nm, and the experiment result was 120.3 nm; the predicted saturation magnetization of the nanoparticles was 80.89 emu/g, the experiment result was 84.09 emu/g at the optimum parameters of NaOH dosage 25 mg/ml, Fe3O4/SiO2 ratio 0.3, Fe2+/Fe3+ ratio 0.5. In general, there is a good agreement between the experimental and the predicted parameters.
