A　novel　cellulose-styrene　copolymer　adsorbent　(cellulose-St)　was　prepared　using　free　radical　polymerization.　Successful　polymerization　was　confirmed　through　Fourier　Transform　Infrared　Spectroscopy　(FTIR),　Carbon　13　Solid　Nuclear　Magnetic　Resonance　(C-13　NMR)　Spectroscopy,　Scanning　Electron　Microscopy　(SEM),　etc.　Cellulose-St　possessed　good　hydrophobicity,　and　the　best　water　contact　angle　of　cellulose-St　samples　could　reach　146　degrees.　It　had　the　ability　of　adsorption　for　nitrobenzene　(NB),　and　the　adsorption　process　could　be　well　described　by　the　pseudo-second-order　(R-2　＞　0.99)　and　three-stage　intraparticle　diffusion　(R-2　＞　0.99)　kinetic　models.　Furthermore,　the　dynamic　adsorption　experiments　revealed　that　cellulose-St　had　the　potential　for　continuous　separation　of　NB　in　water,　and　the　breakthrough　point　for　the　initial　NB　concentration　of　10　mg/L　reached　1.275　L/g.　Moreover,　cellulose-St　exhibited　excellent　environmental　adaptability　that　it　could　maintain　its　hydrophobicity　and　adsorption　ability　for　NB　in　strong　acids,　strong　alkalis,　or　organic　solvents.　The　used　cellulose-St　could　be　reused　after　washing　with　ethanol　and　keep　almost　constant　adsorption　capacity　after　ten　cycles.
