Abstract

Nonuniform electric field formed near pores of a metal-coated track-etched membrane retains on the membrane surface particles having a higher dielectric permittivity compared with the surrounding medium. A feasibility of separating suspensions (for example, rutile slurry in distilled water) by dielectrophoresis on metal-coated track-etched membranes has been experimentally shown.
