Abstract
Maltodextrin was modified by grafting with acrylamide to improve the swelling characters. The conditions of grafting such
as monomer concentration, initiator ratio 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 maltodextrin. The structure of these compounds was investigated using FTIR. The optimum condition of grafting
ratio of maltodextrin to acrylamide monomer1:6g/g, ratio of maltodextrin to initiator 1:0.03g/g, grafting time three hours and
grafting temperature was 70ᴼC. The obtained graft copolymers were used as adsorbents for the removal of Cu(II), Co(II) and
Cr(III) ions from 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.
Adsorption data for adsorbate concentration are most commonly described by adsorption isotherm, such as the Langmuir,
Freundlish and Tempkin isotherms.
