Abstract: The present invention relates to an ion exchange device for purifying water by reducing the nitrite and/or nitrate content, consisting of at least one container with a basic anion exchanger in chloride and/or sulphate form arranged therein and at least one additional basic anion exchanger layer in hydroxyl form or a hydroxyl-group-containing layer, in which the anion exchanger layers are arranged one behind the other directly and/or with the interposition of an intermediate layer and the anion exchange layer(s) in chloride and/or sulphate form is/are arranged not as a mixture but in (a) separate layer(s). The chloride and/or sulphate containing layer is arranged near or beneath the inlet aperture, preferably beneath the filter layer and/or (in the direction of flow of the water) in front of the anion exchange layer in the form of hydroxyl or containing hydroxyl groups. This invention also relates to processes for manufacturing and for using the ion exchange device to remove nitrates and/or nitrates from water.

Abstract: Disclosed are novel ion-exchange and chelate-exchange resins having improved exchange kinetics for separating chemical species from liquids. The resins are prepared from copolymer beads consisting of a monovinyl aromatic monomer and a cross-linking monomer. The copolymer beads are functionalized such that weak-base exchange moieties are substituted at haloalkylated sites which are most accessible to diffusion into the beads, while hydrophilic, strong-base exchange moieties are substituted at haloalkylated sites which are least accessible to diffusion. The resins have improved exchange kinetics due to shortened diffusion path lengths for the chemical species being separated and improved diffusion into the resin beads due to the hydrophilic, strong-base exchange moieties.

Abstract: Porous organic microspheres for use in HPLC are formed by coacervating a colloidal silica sol in a uniform mixture of the sol and a polymerizable organic material. The silica particles which formed the sol are removed from the microspheres with ammonium bifluoride. The remaining organic microspheres are rigid, have uniform pore sizes and distribution, and do not swell or shrink in the presence of the solvents used in HPLC.

Abstract: Disclosed is a process for removing selenium from wastewater effluent. The processd includes the steps of;(i) contacting a selenide containing wastewater and a strong-base anion exchange resin to absorb selenide on the resin;(ii) eluting the ion exchange resin with an eluant which is effective for stripping selenide therefrom; and(iii) recovering elemental selenium from the selenide containing eluate resulting from step (ii). Also disclosed is a process for regenerating the ion exchange resin by treatment of the resin with an acidic chlorate solution.

Abstract: A combined membrane/sorption process is used to selectively remove ions from liquid streams. As an example, nitrate ions can be more effectively removed from an aqueous stream also containing sulfate ions. Sulfate ions normally are not required to be removed from drinking water, but are typically sorbed by the available ion exchange resins and result in inefficient use of the ion exchange capacity. The disclosed process and apparatus use an ion selective membrane to first remove the sulfate ions from the stream and then remove the nitrate ions by ion exchange.
