Abstract:
A sorbent polymer is provided that interacts or reacts with aqueous urea to aid the regeneration of a dialysate liquid. The sorbent polymer may include one or more specific functional groups bonded thereto. Such specific functional groups are selected from carboxylic acids, carboxylic acid esters, carboxylates, amides, dicarboxylic acids, dicarboxylic acid esters, and dicer boxylates to produce the desired urea sorbent.
Abstract:
In a method of regenerating a carbon slurry (14) used to produce a black matrix-type phosphor screen of a cathode ray tube, excess carbon slurry is collected (21) after the completion of carbon-coating of a cathode ray tube panel (11) and the collected carbon slurry is regenerated by means of an ion-exchange resin. The method can be employed in an apparatus for producing the screen, the apparatus including a nozzle (17) for coating the slurry (14) on the panel (11), a tank (13) containing the slurry, a supplying system (16) for supplying the slurry from the tank to the nozzle, a collecting system (21) for collecting the excess slurry produced from the nozzle back into the tank, and a carbon slurry regenerating device (24) using the ion-exchange resin. The regenerating device (29) can be placed in at least one of the supplying system (16), the collecting system (21) and the tank (13).

Abstract:
A sorbent for removing microorganisms and inorganic and organic impurities from water is based on activated carbon and ion exchangers, and comprises: activated carbon in the form of activated carbon with hydroxyl anion exchange groups; and ion exchangers in the form of hydrogenous and calcium-based cation exchange agents, and hydrocarbonate or carbonate anion exchange agents. These raw materials are in the following amounts (parts by weight): cation exchange agent (hydrogenous) 0.02-0.09; cation exchange agent (calcium-based) 0.1-0.5; anion exchange agent (hydrocarbonate or carbonate) 0.1-0.5; activated carbon with hydroxyl anion exchange groups 1.0. The water purification device comprises a housing (1) with an inlet (4) and outlet (6). Inside the housing at the outlet (6) end, a unit (7) for stabilizing the outlet flow rate is fitted; the unit consists of a porous layer (8) and a baffle (9). The latter is supported on ledges on the inner face of the housing (1) and is secured with lugs (11). The baffle (9) is covered with the four-component sorbent described above. Water is purified by being allowed to pass through the sorbent layer (12).

PURPOSE: An ion exchange film-filling composition is provided to provide an ion exchange film which has maximized ion transfer performance in a non-aqueous system, is organic-based, and has film physical properties. CONSTITUTION: An ion exchange film-filling composition comprises an ion conductive material(120) and an aqueous support(130). The ion conductive material comprises at least one compound selected from an ion conducting monomer and an ion conducting polymer. The ion conducting monomer comprises quaternary ammonium salt. A manufacturing method of an ion exchange film comprises a step of impregnating the ion exchange film-filling composition into a porous substrate film(110) which has ion exchanging performance; and a step of polymerizing the ion exchange film-filling composition.
