Preparation of A Spherical Cellulose Adsorbent as Amino Acid Sorbent
The spherical cellulose adsorbent was prepared by grafting acrylic acid onto the spherical cellulose beads prepared by NMMO method. The effecting factors, e.g., monomer concentration, initiator concentration, reaction temperature and reaction time were optimized by the orthogonal and signal-factor experiments and the structure of the adsorbent was characterized by FTIR and SEM. The graft mechanism was also discussed. Moreover, the spherical cellulose adsorbents were shown to behave as good sorbents for basic amino acids L-Arg, L-Lys and L-His.
