Glycidyl methacrylate was grafted on cellulose nonwoven materials in its emulsion state. Amine-type adsorbents for mercury removal were synthesized by reacting the obtained GMA-grafted cellulose with ethylenediamine (EDA) and diethylenetriamine (DETA). The amounts of the amine contents were 2.9 mol/kg-adsorbent for EDA type and 2.8 mol/kg-adsorbent for DETA type respectively. The adsorbents were put in the mercury solution of 100 ppb to evaluate the adsorption selectivity. The adsorption performance was highest at pH3 and the distribution coefficient in pH3 became 1.910 $^{5}$ for EDA type and 2.310 $^{4}$ for DETA type, respectively.
