Abstract: A new adsorbent, bead cellulose loaded with Fe hydroxide (β-FeOOH) was prepared and used for the removal of arsenic from groundwater.Column experiments indicated that the adsorbent had higher efficiency of eliminating both arsenite and arsenate than other adsorbents reported in literature.High bed volumes of 2200 BV and 5000 BV up to a breakthrough concentration of 10 μg•L^-1 were achieved for the arsenite and arsenate removal in the studies with groundwater arsenic concentration of 500 μg•L^-1 while the empty bed contact time were 4.2 min and 5.9 min respectively.While 250 μg•L^-1 of arsenite and 250 μg•L^-1 of arsenate were spiked together in the groundwater and the empty bed contact time was 5.0—5.2 min, the breakthrough volumes up to 50 μg•L^-1 were 7000 BV，6000 BV and 6700 BV respectively for three column recycles.The adsorbent could be regenerated with 2 mol•L^-1 NaOH solutions efficiently.
