Radiation synthesis of amino-functionalizated adsorbent and their application to palladium ions' recovery

In order to prepare a new type adsorbent with an imine affinity ligand for treatment of Pd (), polypropylene (PP) fabrics modified with amine were prepared by radiation-induced grafting of acrylonitrile (AN) onto polypropylene fabrics and subsequently amination of poly-AN graft chains. Influence of some parameters such as initial concentration and adsorption time on the absorbed amount for palladium ions was investigated. Results suggested that the chelating adsorbent possessed high-adsorption performance toward palladium ions. The grafted and aminated fabrics were characterized by FT-IR and DSC.
