Removal of silver(I) and lead(II) Ions by modified polyacrylonitrile from aqueous solutions

It is well known that chelating resins with complex ligands containing sulfur, nitrogen, and oxygen atoms have excellent sorption selectivity for transition metal cations due to thestrong affinity between sulfur, nitrogen, and oxygen atoms and metal ions. Several functional groups such as diethylenetriaminetetraacetic[1], monoethanolamine [2], diethylenetriamine[3] and Ethylenediaminetetraacetic acid[4] have been used for metal ions adsorption. The aim of thiswork is to prepare functionalized polyacrylonitrile with amine groups and to get more information on its adsorptionproperties of transition metal ions from aqueous solutions.
