Effect of Ti Atoms on Néel Relaxation Mechanism at Magnetic Heating Performance of Iron Oxide Nanoparticles
نویسندگان
چکیده
The study was based on understanding the relationship between titanium (Ti) doping amount and magnetic heating performance of magnetite (Fe3O4). Superparamagnetic nanosized Ti-doped ((Fe1?x,Tix)3O4; x = 0.02, 0.03 0.05) particles were synthesized by sol-gel technique. In addition to (Fe1?x,Tix)3O4 nanoparticles, SiO2 coated nanoparticles produced as core-shell structures understand effects silica coating properties nanoparticles. Moreover, associated with Néel relaxation mechanism due ability single-domain state terms results, it observed that induced RF field for (Fe0.97,Ti0.03)3O4 caused an increase in temperature difference (?T), which reached up 22 °C 10 min. ?T values very close uncoated Fe3O4

Adsorption and Desorption Process of Chromium Ions Using Magnetic Iron Oxide Nanoparticles and Its Relevant Mechanism
In this study adsorption of Cr(VI) from aqueous solution by Fe3O4 nanoparticles was investigated. Desorption process and recovery of nanoparticles using different solutions were then carried out, and it was observed that NaOH (0.5M) can remove 90% of adsorbed chromium ions. Following the completion of adsorption/ desorption cycles, it was determined that nanoparticles have still had a high abil...
