Abstract
The invention discloses a preparation method of nanometer ferroferric oxide. The method comprises the following steps: mixing a ferrous compound and a ferric iron compound; with aqueous alkali as a precipitator, agitating and centrifuging at a high speed to obtain the precipitate, wherein the ferrous compound and the ferric iron compound are sulfate or phosphate. The nanometer ferroferric oxide prepared by the method is narrow in particle size distribution, regular in form, and high in dispersing performance, and effectively avoids further agglomeration of particles; the nanometer ferroferric oxide is in a form of superparamagnetic mesoporous nanoscale particles which are high in hydrophilia and suitable for biological application.
Description
Technical field
The present invention relates to nano material preparing technical field, be specifically related to a kind of preparation method of nano ferriferrous oxide.
