In this work, magnetic (Fe3O4) nanoparticles chloride salts deposited using both two-and trivalent manganese and iron were produced in an alkaline environment. The surface layer of silica nanoparticles with improved chemical stability and improved dispersion in the reaction medium were covered. Where the hydrolysis of Tetraethyl orthosilicate (TEOS) was used, which effectively bind with the outer surface of the magnetic nanoparticles and the cover them. In the next part of this investigation the nanoparticle surface by 3- amino propyl trimethoxy silane (APTMS), and finaly...
