Times Cited Count：52 Percentile：81.56(Chemistry, Applied)Fibrous arsenic(As) adsorbent was synthesized by loading zirconium(Zr) on fibrous phosphoric adsorbent which was directly synthesized by radiation-induced grafting of 2-hydroxyethyl methacrylate phosphoric acid on polyethylene-coated polypropylene nonwoven fabric. Zirconium reacted with phosphoric acid grafted in the polyethylene layer. Zirconium density of the resulting adsorbent was 4.1 mmol/g. The breakthrough curve of As(V) adsorption was independent of the flow rate up to 1300 h
in space velocity. The total capacity of As(V) was 2.0 mmol/ g-adsorbent at pH of 2. The adsorbed Zr(IV) could be evaluated by 0.4 M sodium hydroxide solution because no Zr(IV) could be found in the eluted solution. Anions of chloride and nitrate interfered the breakthrough capacity.

Radiation induced graftpolymerization is a sophisticated tool for introducing the aiming functional group into the conventional polymer. Adsorbent having phosphoric acid was directly synthesized by grafting methacrylate monomer having phosphoric acid onto polyethylene nonwoven fabric. Degree of grafting, which was estimated by increment weight after grafting, reached 185 % when the 10 % monomer in the mixture of 10 % methanol and 90 % water was reacted with 200 kGy-irradiated polyethylene nonwoven fabric. The resulting adsorbent revealed that adsorption capacities were 3 mmol/g-adsorbent for Pb and Cd. The removal of these metals could be performed with space velocity of 250 h.
