| 摘要 |
In the present invention, a solution containing a target substance is atomized into a mist by ultrasonic oscillation in an ultrasonic atomization chamber, and the target substance is collected by aggregating the atomized mist in a collection chamber, whereby the target substance is separated from the solution. Further, in the present invention, the gas phase pressure in the collection chamber is maintained to be higher than an atmospheric pressure, whereby the saturation vapor pressure of the target substance in the gas phase is made lower than the saturation vapor pressure under atmospheric pressure.
