| Abstract: | In recent years,water resources crisis is aggravated.As a low energy consuming and a green energy technology,the forward osmosis(FO) separation technology has obvious advantages compared to the reverse osmosis(RO) separation technology in seawater desalination.FO has attracted worldwide attention and is one of the hot of study of membrane separation technologies.In this review,the state-of-the-art in FO membrane materials was summarized from the perspective of the relationship between structure and properties of them,and the common types of draw solution were analyzed.The latest applications and development prospects of FO were also introduced. |
