Abstract: An ultra-thin anion exchange membrane incorporates functional additives to provide improved water management. Without the functional additives the ultra-thin membrane may have high cross-over and not be effective for many applications. A composite anion exchange membrane includes a porous scaffold support such as a porous polymer. The anion exchange polymer may be coupled to the porous scaffold, such as by being imbibed into the pores of the porous scaffold. The functional additives may contribute to increase water production, water retention, back-diffusion and reduce the gas crossover. A functional additive may include a reactive species, including a catalyst that reacts with oxygen or hydrogen, a plasticizer, a hygroscopic material and/or a radical scavenger.

Abstract: A weak base anion resin has alkylamine segments covalently bound to cross-linking segments, the alkylamine segments being selected from a group consisting of: vinylamine, N-methylvinylamine, N,N-dimethylvinylamine, N-methyl-N-ethylvinylamine, and N,N-diethylvinylamine, and the weak base anion resin including ions adsorbed to the alkylamine segments. A method for ion exchange includes providing a weak base anion resin, contacting the weak base anion resin with a solution containing ions to one of capture or adsorb ions from solution to the weak base anion resin, and regenerating the weak base anion resin. A method to capture and release an acid gas includes providing a weak base anion resin, contacting the weak base anion resin with a gas including an acid gas to one of capture or adsorb the acid gas from the gas to the weak base anion resin, and regenerating the weak base anion resin to release the acid gas.

Abstract: Provided are methods of removing perchlorate from water. The methods include contacting water suspected of containing perchlorate with a cationic material. The cationic material includes one or more cationic metal atoms connected by an atom or molecule into an extended structure, and a charge balancing anion. The contacting removes perchlorate (e.g., selectively), if present, from the water. Water treatment vessels, systems and facilities that find use in practicing the methods of the present disclosure are also provided.

Abstract: The present invention provides a technique which allows stable use of an ion-exchange resin for removing boron impurities over a long period of time in the purification step of a silane compound or a chlorosilane compound. In the present invention, a weakly basic ion-exchange resin used for the purification of a silane compound and a chlorosilane compound is cleaned with a gas containing hydrogen chloride. When this cleaning treatment is used for the initial activation of the weakly basic ion-exchange resin, a higher impurity-adsorbing capacity can be obtained. Further, use of the cleaning treatment for the regeneration of the weakly basic ion-exchange resin allows stable use of the ion-exchange resin for a long time. This allows reduction in the amount of the resin used in a long-term operation and reduction in the cost of used resin disposal.

Abstract: A method for the removal of a substance, which has a negative charge and which is present in an aqueous liquid (I). The method comprises the steps of: (i) contacting the liquid with an anion-exchanger (1) that comprises mixed mode anion-exchanging ligands in which there is a positively charged nitrogen allowing binding of the substance to the anion-exchanger; and (ii) desorbing said substance from said anion-exchanger. The characteristic feature is that (A) the mixed mode ligands have a thioether linkage within a distance of 1-7 atoms from their positively charged atom, and (B) the anion-exchanger (1) (i) is capable of binding the substance of interest in an aqueous reference liquid (II) at an ionic strength corresponding to 0.25 M NaCl, and (ii) permits in the pH interval 2-12 a maximal breakthrough capacity for the substance which is ≧200% of the breakthrough capacity of the substance for Q-Sepharose Fast Flow (anion-exchanger 2).
