The present invention relates to a thermo-responsive draw solute that can be applied to water desalination and purification based on forward osmosis. The thermo-responsive draw solute has a molar mass of 50 to 3000 g/mol and undergoes a phase transition at a temperature of 0° C. to 70° C. The thermo-responsive draw solute creates optimum conditions for the desalination of seawater and the purification of contaminated water based on forward osmosis. The present invention also relates to a method for water desalination and purification using the thermo-responsive draw solute. The method consumes little energy for water desalination or purification, is simple to apply to water desalination or purification, and enables separation of the draw solute in a very easy manner.
本发明涉及一种热响应性抽提溶质,可应用于基于正渗透的水淡化和净化。该热响应性抽提溶质的摩尔质量为50至3000克/摩尔,在0°C至70°C的温度下发生相变。该热响应性抽提溶质为基于正渗透的海水淡化和受污水净化创造了最佳条件。本发明还涉及一种利用热响应性抽提溶质进行水淡化和净化的方法。该方法对水淡化或净化消耗少量能量,简单应用于水淡化或净化,并能够非常容易地分离抽提溶质。
