Using the analytical centrifuge to characterize of magnetic particles

Popis výsledku v původním jazyce

Magnetic Fe3O4 nanoparticles were prepared by co-precipitation method according to the literature. Prepared Fe3O4 nanoparticles were dispersed in water solution of surfactant. The dispersion system was characterized by the analytical centrifuge LUMiSizer(LUM, Germany). The separation process of the magnetic nanoparticle dispersion was characterized by the very polydisperse sedimentation (no sharp front) of particles with relatively narrow particle size distribution of fine particles which move with different speed. This type of sedimentation points out colloidal stable dispersions against particle aggregation. Prior to separation, particle concentration was equally distributed along the complete sample length, i.e. transmission was constant at a low level (first transmission profile with the lowest transmission). During sedimentation, the concentration of particles decreased in the region of meniscus and transmission increased. The last profile (highest transmission) indicated that th
