Nanosized polymer particles have attracted great attention as catalysts, colorants, pesticides, electro photography, micro electromechanical systems, and biosensor. Such applications frequently require large particle surface areas, which necessitates the formation of pores in the bead structure. The removal of heavy metal ions from aqueous solution, either for pollution control or for raw material recovery, has been increasing importance in recent years. Sodium methallyl sulfonate (SMS) and poly(ethylene glycol) diacrylate (PEGDA) were used as monomers without further purification. The SMS-co-PEGDA nano particles were synthesized different mole ratio by suspension polymerization. The chemical structure of ion exchange bead was investigated by means of Fourier transform infrared (FT-IR) spectrometry. The ion exchange capacity(IEC) and water uptake were measured. The IEC and water uptake values were increased with increasing SMS mole ratio due to ionic group (-SO3H). |
