Abstract: | A novel spherical cellulose adsorbent has been prepared by homogeneous graft polymerization of N,N'-methylenebisacrylamide(MBA) onto cellulose in an ionic liquid, 1-N-butyl-3-methylimidazolium chloride(BMIMCl), which was then partially amine methylated through Mannich reaction to get bifunctionalized materials containing both amide and sulphinate moities. Factors affecting the attachment of functional groups were investigated. The adsorbent was characterized by Elemental Analysis(EA), Fourier Transform Infrared Spectroscopy(FTIR) and Scanning Electron Microscope(SEM). Cellulose adsorbent was then tested for its potential applications in the reduction adsorption of trichloroacetic acid(TCAA) from aqueous solutions. |
