Abstract: There is provided a method for obtaining a purified aqueous solution of silicic acid containing less metal impurities such as Cu and Ni using water glass as a raw material with less number of purification steps than that in conventional methods without using any unnecessary additives. The method for producing a purified aqueous solution of silicic acid, the method comprising the steps of: (a) passing an aqueous solution of alkaline silicate having a silica concentration of 0.5% by mass or more and 10% by mass or less through a column filled with a polyamine-, iminodiacetic acid-, or aminophosphoric acid-type chelating resin, and (b) passing the aqueous solution passed in the step (a) through a column filled with a hydrogen-type cation exchange resin.

Abstract: In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.

Abstract: The present invention provides efficient reaction conditions by clarifying a relationship between a contact time and an optimum particle diameter etc. in a method for reacting a reaction object with a liquid containing the reaction object being in contact with a granular porous body. The upper limit D (mm) of the particle diameter of the granular porous body is determined from D=0.556×LN (T)+0.166 in a column flow method in non-circulation type, and determined from D=0.0315×T+0.470 in the column flow method in a circulation type and a shaking method. The contact time T (seconds) is given by a value obtained by dividing the volume (m3) of the granular porous body by the flow rate (m3/second) of the liquid in the column flow method in non-circulation type, given by a value obtained by multiplying the fluid flow time (seconds) of the liquid by a volume ratio obtained by dividing the volume of the granular porous body by the volume of the liquid in the column flow method in a circulation type, and given by a value obtained by multiplying the volume ratio by the elapsed time (seconds) after addition of the granular porous body in the liquid in the shaking method.

Abstract: A method of sorbent dialysis is provided for enhanced removal of uremic toxins, such as toxic anions and/or organic solutes, from spent dialysate. More highly adsorbable zirconium polymeric complexes of these anions and/or organic solutes can be initially formed in spent dialysate by treatment with zirconium salt solution or other zirconium cation source, and then removed with adsorbent to provide purified or regenerated dialysate. Sorbent dialysis systems for detoxifying spent dialysate containing toxic anions and organic solutes are also provided.
