Abstract
A super absorbent polymer material is contacted with an aqueous medium to absorb at least a portion of the aqueous medium. At least portion of the aqueous medium absorbed super absorbent material is subsequently regenerated to release water therefrom and to form a regenerated super absorbent material suitable for the contacting with a second quantity of an aqueous medium. Also disclosed are layered composites including an electrically conductive metal support layer, a layer of super absorbent material disposed thereon, and a layer of a selective semi-permeable material disposed adjacent the layer of the super absorbent material and spaced apart from the electrically conductive metal support layer.
