Abstrakty
Sedimentation of nanoparticles in water solutions was studied in situ by transmission Mössbauer spectroscopy in horizontal and vertical geometry. The studied specimens were Fe2O3 of a commercial pigment and metallic iron nanoparticles in slurry used in a water purification technology. The sedimentation is selective and leads to the gradual removing of the bigger particles from a solution. The iron nanoparticles in the solution are relatively chemically stable until, due to the drying, the sediment becomes exposed to the air.
