Abstract
A desalination method includes: introducing a liquid to a reservoir layer to place the liquid above a water-repellent particle layer; heating and evaporating the liquid placed above the water-repellent particle layer to generate water vapor and deposit impurities on the sheet; liquefying the water vapor by a liquefying layer to obtain fresh water; and removing the sheet on which the impurities have been deposited from a desalination apparatus.
