Designing cross-linked polymers capable of absorbing large amounts of water and selectively binding or transporting chemical species across the gel matrix is the major focus of this research. The objective was to synthesize hydrogels with specific functionality, and evaluate their absorption and separation capabilities of ordnance related compounds and some toxic metal ions from aqueous streams. Details of synthesis and characterization of hydrogels (N-Isopropylacrylamide (NIPA) cross-linked with poly (ethylene glycol) methylether acrylate, (PEGMEA)) will be presented. These gels were characterized using SEM, FTIR, and 1H NMR. Results of evaluation of the gels for their water absorption capacity, critical solution temperature, and pH response will be presented. We anticipate our efforts will enhance an understanding of the synthesis and modification of hydrogels with specific functional groups, and facilitate development of cost effective technologies to address the Army's need for detection, monitoring, and treatment of energetic and toxic metal compounds in aqueous streams.
