Claim 12:
13. A desalination method using a solvent extraction scheme, the desalination method comprising:
an operation of supplying first source water comprising salt of a first concentration and water and a functional solvent of which solubility in water varies according to temperature;
an operation of generating mixture water by mixing the first source water and the functional solvent;
a first separation operation of receiving the mixture water and dissolving the water contained in the first source water in the functional solvent at a first temperature to separate the mixture water into lavers; and
a second separation operation of receiving the functional solvent in which the water has been dissolved, and thermally separating the water and the functional solvent at a second temperature that is higher than the first temperature.
