Abstract
A novel method for D-glucose (D-Glu) and trimethylammonium chloride immobilization onto the surface of cellulose powder was studied. Cellulose powder was grafted with vinyl monomer glycidyl methacrylate (GMA), using ceric ammonium nitrate as an initiator, and further derived with quaternary ammonium groups to build the D-GluN+-type cellulose absorbent (Cell-g-GMA-D-GluN+). Epoxy cellulose was found to contain 5.48 mmol/g epoxy groups. The adsorption process of modified cellulose was described by the Langmuir model of adsorption well, the maximum adsorption capacity of chromium (VI) reaching a value of 71.79 mg/g. Adsorption–desorption tests of the D-GluN+-type cellulose derivatives showed a good reproducibility of the adsorbent, so that the adsorbent could be reused for at least six times.
