Abstract: An extracted material for forward osmosis is provided. The extracted material includes a first ionic compound, a second ionic compound and a third ionic compound, which are represented by formula {K[A+(R1)(R2)(R3)]p}(X−)c(Y−)d. X− is the same as Y− in the first ionic compound. X− is the same as Y− in the second ionic compound. X− in the first ionic compound is different from X− in the second ionic compound. X− differs from Y− in the third ionic compound. X− in the third ionic compound is the same as X− in the first ionic compound or X− in the second ionic compound. Y− in the third ionic compound is the same as Y− in the first ionic compound or Y− in the second ionic compound. A method for preparing an extracted material and a forward-osmosis water desalination system using the same are also provided.
