Abstract:
An ion exchanger includes a sheet-shaped positive ion exchanger 2 in which binder particles 5 and positive ionic exchange resin particles 4 are mixed with each other, and a sheet-shaped porous negative ion exchanger 3 in which binder particles 7 and negative ionic exchange resin particles 6 are mixed with each other, the positive ion exchanger 2 and the negative ion exchanger 3 are bonded to each other to form an interface, and capacity of the negative ion exchanger 3 is greater than that of the positive ion exchanger 2. Therefore, the porous ion exchanger 1 is formed and absorbing ability of ion is increased, capacity of the negative ion exchanger 3 is made greater than that of the positive ion exchanger 2, regenerating ability of the ion exchanger with respect to absorbing ability of ion can be secured, and ion absorption and regeneration processing is carried out efficiently.

Methods of making functionalized support material are disclosed. Functionalized support material suitable for use in chromatography columns or cartridges, such as in a high pressure liquid chromatography (HPLC) column or a fast protein liquid chromatography (FPLC) column, is also disclosed. Chromatography columns or cartridges containing the functionalized support material, and methods of using functionalized support material, such as a media (e.g., chromatographic material) in a chromatography column or cartridge, are also disclosed.
Abstract:
A process for the hydrolysis of xylose/arabinose-containing polymers, present in biomass material. The hydrolysis is performed by acid which is generated via salts present in the substrate, and whereby acid is constantly recycled, thereby strongly reducing salt discharge.
Abstract:
A condensate demineralization method for a condensate treatment of a nuclear power generation plant, including: passing condensate at a linear flow rate ranging from 20 m/h to 200 m/h through a condensate demineralization apparatus comprising an ion exchange resin layer filled therein wherein the ion exchange resin layer includes a mixed bed of a strongly acidic cation resin and a strongly basic anion resin and a metal doped resin in a volume ratio ranging from 2% to 50% relative to the mixed bed.
Abstract:
Embodiments of the present disclosure include a process for removing iron ions from an organic stream by contacting the organic stream with an ion exchange resin prior to contacting the organic stream with a peroxide solution including a stabilizer.
Abstract:
The invention is directed to a method for recovering carboyxlic acid from an magnesium carboxylate containing aqueous mixture, including the steps of: contacting the aqueous mixture with an acidic ion exchanger, thereby forming a carboxylic acid mixture and an ion exchanger loaded with magnesium ions; contacting the ion exchanger loaded with magnesium ions with a hydrochloric acid solution, thereby forming a magnesium chloride solution; and thermally decomposing the magnesium chloride solution at a temperature of at least 300° C., thereby forming magnesium oxide (MgO) and hydrogen chloride (HCl).
Abstract:
The present invention provides novel methods of cell disruption and release of biomolecules from a cell. The invention comprises the use of positively and/or negatively charged microparticles comprising ground resin. It is particularly useful for purification of biomolecules from cell culture.
Abstract:
Methods and systems for employing softened acidified water sources from an acid regenerated ion exchange resins are disclosed. Various methods of dispensing and/or using the softened acidic water generated by an acid regenerate-able ion exchange resin are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, including water conditioning agents, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.
Abstract:
An ion-exchange water purification method and system. Feed water is exposed in countercurrent to active media in a vessel, resulting in treated water and spent media. The treated water flows upwards in the vessel and is recovered. The spent media flows to a regeneration zone of the vessel below the active media and is exposed to a regenerant in the regeneration zone, resulting in regenerated media and spent regenerant. The regenerated media flows to a point above the active media and from the point above the active media toward the active media while treated water flows upwards in countercurrent from the active media toward the regenerated media, rinsing the regenerated media and resulting in rinsed media and rinse water. The rinsed media flows to the active media and is combined with the active media.
Abstract:
The present invention relates to a continuous ion exchange methodology for production of ammonium-potassium polyphosphate solutions using agricultural grade phosphoric acid, anhydrous ammonia, and agricultural grade potassium chloride (ag potash) as primary feedstocks. The method is particularly applicable to the production of these low salt index, specialty liquid fertilizer solutions and allows for the use of less expensive ag-potash and impure phosphoric acid as the potassium and phosphate sources in order to produce the ammonium-potassium polyphosphate compounds, which are chloride free as a result of the ion ex-change process.
