Abstract
An adsorbent for radioactive nuclides incorporating fibrous activated carbon. The adsorbent includes fibrous activated carbon having good adsorption performance, inorganic fiber and inorganic binder. Therefore, the adsorbent exhibits good shape stability when it is formed into a molded piece, has good combustion performance, and is not liable to scattering of radioactive nuclides adsorbed thereon when it is incinerated.
Claims6
An adsorbent for adsorption of radioactive nuclides, wherein said adsorbent is produced by a process which comprises mixing 50 to 77 parts by weight of fibrous activated carbon, 20 to 47 parts by weight of inorganic fibers, and 3 to 15 parts by weight of inorganic binder to a total of 100 parts by weight, and molding the mixture into a cylindrical or tubular cartridge configuration.
An adsorbent for adsorption of radioactive nuclides, wherein said adsorbent is produced by a process which comprises mixing 50 to 89 parts by weight of fibrous activated carbon and 10 to 40 parts by weight of inorganic fibers, molding the mixture into a cylindrical or tubular cartridge configuration, then impregnating the molded form with 1 to 15 parts by weight of an inorganic binder to a total of 100 parts by weight.
