Add to ORKGRecycle of rice husks as an adsorbent of metallic ion was studied. Cellulose contained in rice husks was phosphorylated by heating with a mixed solution of DMF (dimethylformamide), phosphoric acid and urea. Phosphorylation of rice husks was extremely improved by milling below 125 microns in a particle diameter and by washing with hot water. Amount of adsorption of metallic ion by rice husks was examined for pH, immersion duration or concent ration of solution. Rice husks phosphorylated showed similar characteristics to typical cellulose hosphorylated, while the adsorbed amount in a unit mass by rice husks constituted 35％ of that of cellulose phosphorylated, since the cellulose content in rice husks was 30％
