Performance of Strong Ionic Hydrogels Based on 2-Acrylamido-2-Methylpropane Sulfonate as Draw Agents for Forward Osmosis

While forward osmosis (FO) has great potential to be the next generation water treatment technology, it is constrained by the development of ideal draw agents and membranes. Herein, a series of copolymerized hydrogels based on strong ionic monomer sodium 2-acrylamido-2-methylpropane sulfonate (AMPS-Na) and thermosensitive monomer
