Abstract

Cellulose powder where modified by grafting with acrylamide to improve the swelling characters. The conditions of
grafting such as monomer concentration, initiator ratio, time of grafting and grafting temperature were evaluated. The
grafting efficiency, The swelling characters as water retention values and sodium binding capacity were determined and
nitrogen content were also evaluated for grafting cellulose powder The structure of these compounds was investigated using
FTIR. The optimum condition of grafting ratio of cellulose powder to acrylamide monomer1:1g/g, ratio of cellulose powder
to initiator 1:0.3g/g, grafting time three hours and grafting temperature was 80◦C.
The obtained graft copolymers were used as adsorbents for the removal of Zn, Mn and Cu ions in an aqueous solution each
one alone. The effect of pH value, contact time, initial metal ion concentration and polymer dosage on metal ions uptake were
reported.
