It rings.Method currently used for preparing nano ferriferrous oxide particle mainly has physical method and chemical method.Wherein, physical method
The nano ferriferrous oxide purity of preparation is low, particle diameter distribution is uneven, so its application range of products is relatively narrow.Chemical method obtains
Product run-of-the-mill it is preferable, operating method is also relatively easy to, thus obtain extensively research and concern;But its also have it is unfavorable
On one side, it as reaction principle is typically more complicated, is not easy accurately to control its pattern and performance.
At present be used to prepare nano ferriferrous oxide chemical method mainly have coprecipitation, hydro-thermal method or solvent-thermal method,
Microemulsion method, sol-gel method etc..Different methods, reaction principle, consersion unit and reaction condition have very big difference,
The pattern and property of product are also not quite similar.
Ionic liquid, that is, the liquid being composed entirely of ions, since it is low with fusing point, electric conductivity is strong, dissolubility is high etc.
Characteristic not available for many usual vehicles, thus be a hot fields of Recent study, it is sent out in compound synthesis field
Wave important function.
Ionic liquid is generally made of organic cation and big inorganic anion, common cation have quaternary ammonium salt from
Son, quaternary phosphine salt ion, imidazolium ion and pyrroles's salt ion etc., anion has halide ion, tetrafluoroborate ion, hexafluoro phosphorus
Acid ion etc..

(2)Divalent iron salt and trivalent iron salt are added separately in ionic liquid to and are stirred 10 ~ 20min, it is molten to obtain divalent iron salt
The concentration of liquid and ferric salt solution, the divalent iron salt solution and ferric salt solution is 0.3 ~ 0.6mol/L;
(3)Divalent iron salt solution and ferric salt solution are uniformly mixed under agitation, while with heating water bath and being kept the temperature
At 30 ~ 40 DEG C, then proceed to be slowly added to powdered analysis pure cerium hydroxide sodium under agitation, after adding keep the temperature 30min ~
2h;
(4)It is centrifugated reaction mixture, by isolated product with heptane wash 2 ~ 3 times, then is washed with deionized 2 ~ 3
It is secondary, it is dried at 40 ~ 60 DEG C to get nano-scale magnetic ferroso-ferric oxide is arrived.
Wherein, the divalent iron salt is one of frerrous chloride, ferrous nitrate, ferrous sulfate or a variety of, the trivalent
Molysite is one of iron chloride, ferric nitrate, ferric sulfate or a variety of.
Further, the ionic liquid is [Bmim] BF4。
Further, step(3)In, the additional amount of the sodium hydroxide is 0.5-1 relative to the mole of divalent iron salt
Times, it is described to be slowly added to be to be added to complete in 10-30min.
Ionic liquid is a kind of solvent of green high-efficient, plays important role in synthesis chemistry, synthesis is each extensively
Kind organic substance, but the research for synthesizing inorganic compound with it so far is still less.The present invention is special using ionic liquid
Property replaces the aqueous solvent in traditional co-precipitation method, conveniently prepares nanoscale magnetic ferroferric oxide particle, grain
Diameter is evenly distributed, and spherical shape is good, by Magnetic Test, has preferable coercivity and magnetic saturation amount, and preparation method is simple,
Equipment requirement is low, is suitable for producing in enormous quantities, is a kind of preparation method with bright prospects.
