This kind of the magnetic field might be used to augment the process intensity instead of a mechanical mixing. One of the advantages of the RMF is the possibility to apply it to generation and control of the hydrodynamic states for the magnetic particle mixing systems. In the experimental procedure, the frequency of the RMF was equal to 50 Hz. The intensity of the magnetic field could be 25 mT. The more detailed information about the experimental setup and the measurements of the magnetic field for the tested apparatus may be found here[48]. Finally, the precipitate was collected by filtration and washed three times with deionized water and then dried
