Abstract
A material is, herein disclosed for collecting radionuclides and heavy metals that comprises an acrylic fiber element having MnO.sub.2 and/or ferrocyanide compound of the formula K.sub.2 M.sup.II [Fe(CN).sub.6 ] (wherein M.sup.II is a divalent metal such as cobalt, zirconium, zinc or nickel) supported thereon. The material of the present invention is used in collecting and concentrating radionuclides present in liquid radioactive wastes discharged from nuclear power plants and other facilities using radioisotopes such as hospitals and non-destructive testing laboratories. The material is also used in collecting and concentrating radionuclides and heavy metals present in the seawater, rivers and industrial waste-water.
Claims15
A material for collecting radionuclides and heavy metals which comprises an acrylic fiber element having fixedly supported thereon at least one ferrocyanide compound of the formula K.sub.2 M.sup.II[Fe(CN).sub.6 ] wherein M.sup.II is a divalent metal selected from the group consisting of Co, Zn, Zr and Ni.
A material for collecting radionuclides and heavy metals which consists of the combination of a collecting material comprising an acrylic fiber element having MnO.sub.2 fixedly supported thereon and a collecting material comprising an acrylic fiber element having fixedly supported thereon a ferrocyanide compound of the formula K.sub.2 M.sup.II [Fe(CN).sub.6 ] wherein M.sup.II is a divalent metal selected from the group consisting of Co, Zn, Zr and Ni.
A material for collecting radionuclides and heavy metals which comprises an acrylic fiber element having fixedly supported thereon MnO.sub.2 and a ferrocyanide compound of the formula K.sub.2 M.sup.II [Fe(CN).sub.6 ] wherein M.sup.II is a divalent metal selected from the group consisting of Co, Zn, Zr and Ni.
