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 mg/g, indicating that the
adsorption capacity of carboxymethyl cellulose was improved remarkably after
grafting poly(acrylic acid). Moreover, Fourier transform infrared spectroscopy
(FT-IR) has been used to investigate the adsorption mechanisms at molecular
levels, which revealed that carboxyl groups are facile to form bidentate
carboxylates with metal ions. Thus, this environment friendly copolymer will be
a promising candidate for application in removal of heavy metal ions.},
