    Abstract: Radioactive strontium is efficiently removed from wastewater containing radioactive strontium. In a treatment method for radioactive strontium-containing wastewater, wastewater containing radioactive strontium and a powdery alkali metal titanate are mixed in a stirrer-equipped reaction tank by stirring such that radioactive strontium in the wastewater is adsorbed on the powdery alkali metal titanate, followed by subjecting the powdery alkali metal titanate having radioactive strontium adsorbed thereon to solid-liquid separation. The radiation dose of treated water can be effectively reduced in such a manner that a powder of an alkali metal titanate is directly added to radioactive strontium-containing wastewater and is dispersed therein and therefore radioactive strontium is efficiently removed by adsorption.

Also disclosed is the reduction of potentially hazardous metal radionuclides metals such as uranium, iodine, cesium, plutonium and radium. Also disclosed is improved removal of heavy metals such as arsenic, lead, chromium, and mercury as well as organic compounds such as halogenated carcinogenic compounds. The present devices and methods remove specific bacteria and their toxins from water to reduce the risk of dermatitis. Thus, the present invention enhances our ability to achieving cleaner and safer water for drinking, swimming, washing, bathing and cooking.

  • Patent number: 8342337
    Abstract: A water sampling device and method for use with a radiation probe. The device includes a base, filtrate reservoir, filter media support disc, and sample reservoir. The sample reservoir may be interchanged with a radiation probe adaptor. The device and method provide a simple and convenient means to separate particulate solids from a water sample prior to measuring radioactivity without the need for a heat source or electrical power to evaporate the water. The device and method can be used with a variety of commercially available radiation probes and is suitable for field applications.

  • Patent number: 8343446
    Abstract: The oxine ligands 5-chloro-8-hydroxyquiniline and 5-sulfoxyl-8-hydroxyquinoline are covalently bound, using, for example, the Mannich reaction, to a silica gel polyamine composite made from a silanized amorphous silica xerogel and polyallylamine. The resulting modified composites, termed CB-1 (X?Cl) and SB-1 (X?SO3H), respectively, show a clear selectivity for trivalent over divalent ions and selectivity for gallium over aluminum. The compounds of the invention can be applied for the sequestration of metals, such as heavy metals, from contaminated mine tailing leachates.

  • Patent number: 8252185
    Abstract: A water treatment apparatus includes a housing comprising multiple housing portions and a plurality of treatment sections disposed within the housing, each treatment section comprising at least one distinct particulate layer. The apparatus is designed so that no water pressure need be applied to force the water through the apparatus, as gravity pulls the water down through the filtering layers. Water may also be force fed through the treatment apparatus; when the water is force fed, the housing portions need not be vertically stacked, but may be configured in any suitable arrangement. The treatment sections are distributed through the various housing portions in logical groups to perform various kinds of filtering. The housing portions are detachable and sealably stackable in multiple configurations, thus passing water through more or fewer treatment layers, depending on the quality of the incoming water.

  • Publication number: 20120125856
    Abstract: A nanocomposite solid material includes nanoparticles of a metal coordination polymer with CN ligands comprising Mn+ cations, in which M is a transition metal and n is 2 or 3; and anions [M?(CN)m]x? in which M? is a transition metal, x is 3 or 4, and m is 6 or 8. The Mnn+ cations of the coordination polymer are bound through an organometallic bond to an organic group of an organic graft chemically attached inside the pores of a support made of porous glass. The material can be used in a method for fixing (binding) a mineral pollutant, such as radioactive cesium, contained in a solution by bringing the solution in contact with the nanocomposite solid material.
