The role of starch in nano-magnetite formation: A spectrometric and structural investigation

In the framework of pollutant sequestration by magnetic nano materials, this work focuses on synthesis and physico-chemical properties starch functionalized magnetites. Nanoparticles were prepared Fe2+/Fe3+ coprecipitation method with increasing amount in medium (starch to iron mass ratio (R) range 0–10). Obtained materials characterized Transmission Electron Microscopy (TEM), Powder X-Ray Diffraction (PXRD), Raman, Fourier Transform Infrared (FTIR) 57Fe Mössbauer spectroscopies, as well vibrating sample magnetometry. The presence into lowers magnetite crystallinity increases dispersion oxide particles. Both effects lead fast relaxing superparamagnetic particles at RT for high R. role nano-magnetite growth stabilization is evidenced.
