Abstract:
A method for concentration of fine particles dispersed in a dispersion into an ionic liquid comprising, adding an ionic liquid, especially an organic ionic liquid at ordinary temperature, e.g., a salt of 1-butyl-3-methylimidazolium with PF6− to a dilute dispersion of fine particles so as to concentrate the fine particles into the ionic liquid.
