Abstract: Disclosed herein are a class of anion exchange resins containing two different exchange sites with improved selectivity and sorptive capability for chemical species in solution, such as heptavalent technetium (as pertechnetate anion, TcO.sub.4.sup.-). The resins are prepared by first reacting haloalkylated crosslinked copolymer beads with a large tertiary amine in a solvent in which the resin beads can swell, followed by reaction with a second, smaller, tertiary amine to more fully complete the functionalization of the resin. The resins have enhanced selectivity, capacity, and exchange kinetics.

Abstract: A method for preparing non-agglomerating mixed bed ion exchange resin systems without affecting the ion exchange kinetics of the anion exchange resin component of the mixed bed system is disclosed. Pretreatment of the anion exchange resin component with a sulfonated poly(vinylaromatic) polyelectrolyte is particularly effective in providing non-agglomerated mixed bed systems without affecting ion exchange kinetics. Treatment levels of 10 to 800 milligrams per liter of anion exchange resin with sulfonated poly(vinylaromatic) polyelectrolyte having number average molecular weight from 5,000 to 1,000,000 are particularly preferred.

Abstract: The present process is designed for removing elemental iodine and iodide ions from an aqueous solution containing iodine and iodide ions. This process employees a strong-base anion exchange resin. The resin comprises trialkyl amine groups each preferably comprising from alkyl groups containing 3 to 8 carbon atoms. The aqueous solution containing elemental iodine and iodide ions is passed through the resin and thereby treats the aqueous solution by removing elemental iodine and iodide ions therefrom. The volume of the aqueous solution passing through the resin until reaching the Breakthrough Point is at least about 8 liters per cubic centimeter.

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: A method is provided for strong base anion exchange resins containing high concentrations of pentaiodide (I.sub.5.sup.-). The resins are prepared from highly concentrated solutions of I.sub.5.sup.- and I.sub.3.sup.- ions. The exchanged ions, such as chloried (Cl.sup.-), are washed out of the resin after completion of the exchange reaction with the polyiodide ion mixture. The resulting product is a stable resin of predetermined I.sub.5.sup.- content, which is highly effective as a disinfectant for water, acting against water-borne bacteria, virus, and Giardia.

Abstract: An improved unit for removal of tannin and lignin from water is disclosed, which features a cylindrical tank containing a tannin/lignin-adsorbing resin bed and a distributor tube/water distributor assembly. The assembly comprises a distributor tube extending from an orifice in the upper portion of the tank to a lower distributor assembly, and a riser tube having an open end disposed near the lower distributor assembly and communicating with an upper distributor located beneath the surface of the resin. A water flow restrictor is provided in the lower distributor assembly, such that when water is passed downwardly through the distributor tube in a backwash mode, some of the water is injected into the riser tube. This causes the backwash water to flow into the resin bed at its lower portion and to carry resin up through the riser tube to the upper portion of the resin bed. In this way, the resin bed is more effectively regenerated by a subsequent supply of a brine solution than if the backwash water were only injected at the lower portion of the resin bed. This improved efficiency allows the tannin/lignin-adsorbing resin bed to adsorb tannins and lignins at significant and acceptable levels even where iron and suspended particulate matter are present in the ground or other inlet water stream.

Abstract translation: 公开了一种用于从水中除去单宁和木质素的改进单元，其特征在于包含单宁/木质素吸附树脂床和分配器管/水分配器组件的圆柱形罐。 组件包括从罐的上部的孔口延伸到下部分配器组件的分配器管，以及设置在下部分配器组件附近的开放端的提升管，并与位于树脂表面下方的上部分配器连通 。 在下部分配器组件中设置有一个水流限制器，使得当水以反冲洗模式向下通过分配器管时，一些水被注入提升管中。 这导致反洗水在其下部流入树脂床，并将树脂通过提升管携带到树脂床的上部。 以这种方式，通过随后的盐水溶液的供给，更有效地再生树脂床，而不是仅在树脂床的下部注入反冲洗水。 这种改进的效率使得单宁/木质素吸附树脂床在显着和可接受的水平下吸附单宁和木质素，即使铁和悬浮颗粒物质存在于地面或其它入口水流中。
