Removal of Chromium (VI) from Aqueous Solution by Cellulose Modified with D-Glucose
Cellulose powder was grafted with the vinyl monomer glycidyl methacrylate using ceric ammonium nitrate as initiator and was further derived with D-Glucose (D-Glu) to build a adsorbent (Cell-g-GMA-D-Glu). Epoxy cellulose, which was made up of Cell-g-GMA and Cell-hydro-g-GMA, was found to contain 5.48mmol g(-1) epoxy groups. The adsorption process of the adsorbent was described by the Langmuir model of adsorption well and the maximum adsorption capacity of chromium (VI) reached to 54.59 mgg(-1). The adsorption-desorption tests of the Cell-g-GMA-D-Glu exhibited that the reproducibility of the absorbent was well and the adsorbent could be reused six times at least.
