    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 More >
