| Research Abstract |
Enhanced metal separation techniques that are energy-saving and environment-friendly are desirable in industrial chemistry, as they can be used in applications to separate valuable metal ions from industrial effluents. Novel emulsion gel adsorbents, that is, polymeric hydrogels containing randomly distributed oil microdroplets of an organic extractant (an oil-soluble complexing agent), were developed for metal adsorption. The emulsion gels successfully adsorbed metal ions from aqueous media. Monodisperse emulsion gel beads, which were approximately 1 mm in diameter, were prepared using a production method combining sedimentation polymerization and two-fluid atomization. A continuous process for adsorption of metal ions from a solution onto emulsion gel beads using the fixed bed method was established and designed.
