Abstract: Cellulose was modified by reaction with (N‐butyl‐N‐chloropropyl‐N,N‐dimethyl) ammonium bromide (BCDMAB). The optimum reaction conditions were as follows: temperature 55°C, reaction time 3.2 h and mass ratio of cellulose:BCDMAB=1:2.5. Equilibrium adsorption capacity of modified cellulose for arsenate ion has been estimated. It's shown that this capacity increased with concentrations of arsenate ion. Structure of modified cellulose was confirmed by IR and SEM images.
