Cellulose　was　first　grafted　with　glycidyl　methacrylate　(GMA)　in　an　ionic　liquid　via　atom　transfer　radical　polymerization　(ATRP)　and　then　the　introduced　epoxy　groups　were　reacted　with　ethanediamine　(EDA)　to　obtain　an　amino　adsorbent.　The　grafting　copolymer　and　the　obtained　adsorbent　were　characterized　by　FTIR,　H-1　NMR,　TEM　and　SEM.　The　results　showed　that　the　grafted　copolymers　had　grafted　polymer　chains　with　well-controlled　molecular　weight　and　polydispersity,　the　polymerization　was　a　controlled　system.　The　cellulose　adsorbent　had　numerous　micropores　on　the　surface　and　showed　high　performance　for　Cr(VI)　adsorption.　The　adsorption　behavior　was　pH　dependent　and　the　sorption　equilibrium　was　achieved　within　2　h　on　the　adsorbent.
