EXTRACTED MATERIAL FOR FORWARD OSMOSIS, PREPARATION METHOD THEREOF, AND FORWARD-OSMOSIS WATER DESALINATION SYSTEM USING THE SAME

摘要

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.
