ABSTRACT
The concept of magnetic separator designed and suitable for analytics and scientific research was presented. The ferromagnetic foil perforated by laser beam was used as a membrane separating unit. The water suspension of magnetite nanoparticles adsorbed on the grains of hydroxyapatite was used to test the magnetic separator designed. To evaluate the separation efficiency, the suspension magnetization and the particles sizes were measured by ferromagnetic resonance and dynamic light scattering, respectively. It was shown that during the separation, all particles larger than 500 nm were captured by the membrane, whereas the total magnetization of the separated fraction was halved.
