In this study, glycidyl methacrylate monomers having epoxide groups were radiation graft polymerized to polypropylene with electron beam. Prepared PP-g-GMA was aminated and sulfonated to give chelate adsorption and ion exchange adsorption properties. Modified PP-g-GMA measured its characteristic of metal adsorption, focused on capacity. Thermogravimetric analysis were used for measure graft yeild and conversion ratio. FT-IR spectrum showed a change in functional group during polypropylene grafting, amination and sulfonation. Functional groups reacted to polypropylene could be verified their types and fraction through X-ray photoelectron spectroscopy. The scanning electron microscopy figure showed change of surface morphology of polypropylene. the result of Inductively coupled plasma mass spectrometry showed quantitative radioactive metal ion adsorption on aminated PP-g-GMA. |
