Preparation method for superparamagnetic ferrite nano particle
The invention discloses a preparation method for a superparamagnetic ferrite nano particle. The preparation method comprises the following step: injecting amino group-terminated alcohol into a polyalcohol solution consisting of ferric iron salts and divalent metal ion salts to prepare the superparamagnetic ferrite (MxFeyO4) nano particle in a controller manner, wherein the particle size of the nano particle is regulated by changing the volume of the injected amino group-terminated alcohol, and the proportion (x:y of (0-1):2) of x to y in the MxFeyO4 is regulated by changing the proportion of the ferric iron salts to the divalent metal ion salts. The preparation method disclosed by the invention is simple in step, good in repeatability, gentle in condition and suitable for large-scale preparation, and can be used for preparing the nano particle under normal pressure.
