It is well known that adsorbents having N-methyl-D-glucamine (NMDG) preferentially adsorb boron. The boron adsorbent developed in this study has promising properties of rapid boron adsorption from the natural water. The adsorbent was prepared by radiation induced graft polymerization of glycidyl methacrylate (GMA) onto non-woven polyethylene fabrics in aqueous medium, and following chemical modification with NMDG The resulting adsorbent was evaluated by column-mode adsorption of boron at various flow rates. Comparison between graft adsorbent and granular resin, graft adsorbent has 4 times higher bed volume (BV) at breakthrough point at space velocity (SV) 50 h<SUP>-1</SUP>. The BV at breakthrough point of graft adsorbent at SV 100 h<SUP>-1</SUP> gave the same one with granular resin at SV10 h<SUP>-1</SUP>.
