摘要： Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.
