Desıgnıng Og Ion-Imprınted Cryogels and Theır Use for Heavy Metal Removal

Abstract

Heavy metals generally are toxic for animal and human body. Heavy metals due to stability and resistance to degradation are classified as environmental toxins. Therefore these metals should be removed from wastewaters.Cryogels are polymeric gel matrices. Cryogels generally have interconnected supermacroporos spongy structure, high pore density, and large pores. Due to their large surface area and low flow resistance, they can be used for fast and high capacity separation. Due to specific ion recognitions ion-imprinted cryogels were used as stationary phases in chromatography. Interaction of template molecule to functional monomer with non-covalent interaction is organized and provides solid materials which have functional groups, then by removing of template ions forms template ion specific regions in polymer.
