Abstract：

The　spherical　cellulose　adsorbents,　used　for　the　removal　of　Cu(II)　from　aqueous　solutions,　were　obtained　by　homogeneous　graft　copolymerization　of　cellulose　with　acryhc　acid　and　followed　by　water-in-oil　suspension　technique.　Various　factors　affecting　adsorption　properties　such　as　pH,　initial　concentration　of　Cu2+,　adsorption　time,　and　adsorption　temperature　were　investigated　and　the　adsorption　thermodynamics　and　kinetics　were　also　explored　in　detail.　The　results　showed　that　the　equilibrium　data　were　well　fitted　to　the　Langmuir　isotherm　and　the　thermodynamic　parameters　were　derived　to　predict　the　nature　of　adsorption　process.　The　kinetics　of　adsorption　followed　pseudo-second-order　model　and　the　adsorption　involved　diffusion　controlled　process.　The　spherical　cellulose　adsorbents　have　good　adsorption　performance　to　Cu2+　as　well　as　regeneration　capacity.
