Method for producing ultrasmall superparamagnetic iron oxide nanoparticles

摘要

process for the production of ultramau0142ych superparamagnetycznych nanoparticles of iron oxide is that the silica mezoporowatej the following two kinds of salt iron mole concentration ratio fe3 + to fe2 + ions equal to 2: 1. then the silica mezoporowatu0105 sonikuje, followed odwirowuje and ignoring the supernatant. residual sludge containing iron salts mezoporowatu0105 silica filled with drought.in turn, subjected to the action of weak rules to precipitate iron oxide nanoparticles. then the silica mezoporowatu0105 roztwarza a strong rule, after which the zol nanoparticles of iron oxide odwirowuje and collected the supernatant containing ultramau0142e superparamagnetyczne nanoparticles of iron oxide.
