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.

Abstract: An ionic liquid and a forward osmosis process employing the same are provided. The ionic liquid has a structure represented by Formula (I) ABn Formula (I) , wherein A is n is 1 or 2; m is 0, or an integer from 1 to 7; R1 and R2 are independently methyl or ethyl; k is an integer from 3 to 8; B is i is independently 1, 2, or 3; and j is 5, 6, or 7. The forward osmosis process employing the ionic liquid is used to desalinate a brine via a forward osmosis (FO) model.

Abstract: A forward osmosis process is provided, which includes separating a feed part and a draw solution part by a semi-permeable film. An ionic liquid is introduced into the draw solution part, and brine is introduced into the feed part. The brine has an osmotic pressure lower than that of the ionic liquid, so that pure water of the brine permeates through the semi-permeable film, enters the draw solution part, and mixes with the ionic liquid to form a draw solution. The draw solution was obtained out of the draw solution part to be left to stand at room temperature, so that the draw solution separated into a water layer and an ionic liquid layer. The ionic liquid includes
