Abstract Biocompatible and high content grafted carboxymethyl cellulose-gpoly(acrylic
acid) powder was successfully synthesized in an aqueous system,
and used as adsorbents for the removal of Cu(II) in aqueous solution. The
copolymer was characterized by FT-IR and SEM techniques. Graft
copolymerization introduced a large number of carboxyl groups in the polymer
and caused the micro-surface of the material to be porous. The fundamental
adsorption behaviors of the material were studied. The adsorption kinetics was
well fitted with pseudo-second order equation, while the adsorption isotherm
preferred to be described the Langmuir equation. The maximum adsorption
capacity obtained from the Langmuir model was 154.32… More >
