摘要
利用水合肼作为还原剂和提供碱性,PVP作为保护剂,在水溶液中还原Fe3+制备出具有超顺磁性能的Fe3O4粒子,XRD检测结果表明其晶粒大小约10 nm,饱和磁强度达到45 emu/g,为超顺磁Fe3O4的水相制备提供了一条新的途径。
By using hydrazine hydrate as basic and reducing agent, PVP as capping reagent, superparamagnetic nano - Fe3O4 was synthesized through a simple method in water. The gain size was calculated at about 10 nm according to XRD results, and the saturation magnetic intensity reached 45 emu/g. This method proved a new way for superparamagnetic nano -Fe3O4preparation.
