Computational Methods for Assessment of Magnetic Forces Between Iron Nanoparticles and Their Influence on Aggregation

Popis výsledku v původním jazyce

Zero-valent iron nanoparticles are being studied and used in frame of groundwater remediation technologies such as permeable reactive barriers and in-situ reagent. Their main advantages are that they would be able to migrate in porous medium and rapidlyreact in-situ due to their huge specific reaction surface. If not modified they rapidly aggregate and lose these properties, so many surface modifications are being suggested to stabilize them. One of the reasons of rapid particle aggregation is strong and long-range attractive magnetic forces among particles. The core of spherical particles is formed by zero-valent iron and their shell is composed from iron oxides, especially magnetite. The paper deals with examination of magnetic forces among bare particles without any surface modification. The magnetic field around an aggregate depends on aggregate structure and on structure of particles constituting the aggregate. We suppose that the magnitude of polarization vector of each single p
