Synthesis and characterization of multi-amino-functionalized cellulose for arsenic adsorption

► A multi-amino-functionalized cellulose was synthesized for the removal of arsenic. ► The aminated cellulose has relative high nitrogen content. ► The adsorbent has a high adsorption capacity for As(V). ► The adsorption capacities of arsenic were less affected by coexisting ions. ► The adsorbent can be efficiently regenerated with NaOH solution.
