A　novel　spherical　cellulose　adsorbent　has　been　prepared　by　homogeneous　graft　polymerization　of　N,　N′-methylenebisacrylamide　(MBA)　onto　cellulose　in　an　ionic　liquid,　1-N-butyl-3-methylimidazolium　chloride　(BMIMCl),　which　was　then　partially　amine　methylated　through　Mannich　reaction　to　get　bifunctionalized　materials　containing　both　amide　and　sulphinate　moities.　Factors　affecting　the　attachment　of　functional　groups　were　investigated.　The　adsorbent　was　characterized　by　Elemental　Analysis　(EA),　Fourier　Transform　Infrared　Spectroscopy　(FTIR)　and　Scanning　Electron　Microscope　(SEM).　Cellulose　adsorbent　was　then　tested　for　its　potential　applications　in　the　reduction　adsorption　of　trichloroacetic　acid　(TCAA)　from　aqueous　solutions.
