Abstract：

An　investigation　was　conducted　on　the　adsorption　of　a　cationic　dye　methylene　blue　(MB)　on　a　spherical　cellulose　adsorbent,　which　was　prepared　by　homogeneous　graft　copolymerization　of　cellulose　with　acrylic　acid　in　an　ionic　liquid　(IL)　l-N-butyl-3-methylimidazolium　chloride　(BMIMC1)　followed　by　spheriodization　of　the　graft　copolymer　by　means　of　the　water-in-oil　suspension　technique.　It　was　found　that　the　adsorption　of　the　MB　on　the　adsorbent　was　solution　pH,　initial　concentration　of　MB,　time　and　temperature　dependent.　The　adsorption　process　followed　the　Langmuir　adsorption　isotherm,　and　was　controlled　by　diffusion　process.　Desorption　and　regeneration　experiments　showed　that　the　MB　adsorbed　on　the　adsorbent　could　be　easily　recovered　by　2.0　mol/L　HC1　aqueous　solution,　and　after　3　replications　of　the　adsorption　and　desorption　process,　the　adsorbent　still　showed　high　adsorption　efficiency　towards　the　MB.
