摘要： The present invention relates to a porous manganese oxide-based lithium absorbent and a method for preparing the same. The method includes the steps of preparing a mixture by mixing a reactant for the synthesis of a lithium-manganese oxide precursor powder with an inorganic binder, molding the mixture, preparing a porous lithium-manganese oxide precursor molded body by heat-treating the molded mixture, and acid-treating the porous lithium-manganese oxide precursor molded body such that lithium ions of the porous lithium-manganese oxide precursor are exchanged with hydrogen ions, wherein pores are formed in the lithium-manganese oxide precursor molded body by gas generated in the heat treatment. The porous manganese oxide-based lithium adsorbent according to the present invention is easy to handle and has many more adsorption reaction sites compared to existing molded adsorbents, thus providing high lithium adsorption efficiency.

摘要： An ion exchange material comprises an oxide of a first element selected from elements of Groups IVa, IVb, Va, Vb, VIa, VIb, VIIa, or lanthanide or actinide series of the Periodic Table, in combination with an oxide of at least one different element selected from elements of the afore-mentioned groups of the Periodic Table so as to form a composite material. For example, a composite ion exchange material may comprise silicon dioxide and manganese dioxide. By selecting the appropriate oxides a composite ion exchange material can be prepared which has greater mechanical and/or chemical stability than an individual oxide of the composite material.

摘要： An inorganic ion-exchanger supported on a carrier suitable for recovery of useful resources in sea water, removal of impurities from high temperature boiler water in nuclear reactors or industrial boilers, removal of impurities in industrial waste water, etc. is prepared by supporting an active component of inorganic ion exchanger, such as hydrous oxide of metal, for example, titanium, zirconium, etc. on a porous carrier such as alumina, silica, or activated carbon, where a pH of a solution in contact with the active component and the carrier is adjusted so that the active component and the carrier can have zeta potentials of opposite polarities to each other, and an inorganic ion-exchanger having a larger amount of the supported active component and firmly supporting less bleedable active component can be obtained by setting out a supporting condition on the basis of the polarity of zeta potential.

摘要： A process for removing Sr2+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchanger to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchanger. The ion exchangers are represented by the following empirical formula: AmZraTibSncMdSixOy. A composition comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution is also disclosed. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.
