Aerosol particles of99mTc-labeled carbon were prepared by sublimation and introduced in various liquid media. The adsorption of the aquasol and organosol
particles were studied for various adsorbing substances and media, with the effect of surface treatment and voltage application.
The particles often accumulated at the aqueous-organic interface, and also on the vessel surface in the presence of both aqueous
and organic phases. The distribution of the particles was examined by a gamma-camera for different organic phases under various
concentrations of electrolytes in the aqueous phase.
