ABS>The dependence of the sorption of molecular iodine by AV-17 anion- exchange resin on the iodine concentration, supporting electrolyte, and temperature was deduced from laboratory and pilot-plant experimental data. (auth)

The ion-exchange studies on uranium and plutonium using macroporous anion-exchange resins from an aqueous-organic solvent mixed media were carried out to develop a method for their separation. Out of the several water miscible organic solvents tried, meth...

Peculiarities of the sorption of methanal on a polyfunctional anion exchanger are investigated. Based on the sorption isotherm, it is established that the distribution coefficient of the aldehyde in the ion exchanger-solution system depends exponentially on the concentration of the external solution. From breakthrough curves of sorption, the ...

The use of glycine as complexing agent for chromatographie separation of palladium from platinum, or palladium from iridium, on cellulose anion-exchangers has been investigated and found possible over a wide range of concentration ratios. The method can be used for analysis of Pd-Ir alloys. The nature of the complexes taking part in the ion-exchange has been identified. ...

Despite early reports, dating back three quarters of a century, of high total CO(2) concentrations in the intestinal fluids of marine teleost fishes, only the past decade has provided some insight into the functional significance of this phenomenon. It is now being recognized that intestinal anion exchange is responsible for high luminal HCO(3)(-) and ...

The interaction of dilute aqueous A/sub 2/O/sub 2/ and ion exchange resins was investigated. A mechanism of absorption and decomposition of H/sub 2/ O/sub 2/ on anion exchange resin is proposed. (auth)

Bis(2-ethylhexyl)phosphoric acid (HDEHP) may be purified by absorption on a macroreticular, strong base anion exchange resin. Properties of ion exchange purified HDEHP are in excellent agreement with literature values.

Studies are summarized in which attempts were made to improve the efficiency of an electrode demineralization process for use in desalination by increasing the anion exchange capacity of anodes prepared from modified carbon black materials. (Author)

Strong base, nitrate anion exchange (IX) is crucial to the purification of {sup 238}Pu solution feedstocks with gross levels of impurities. This paper discusses the work involved in bench scale experiments to optimize the nitrate anion exchange process. In particular, results are presented of experiments conducted ...

Anion exchangers are membrane proteins that have been identified in a wide variety of species, where they transport Cl(-) and HCO3- across the cell membrane. In this study, we cloned an anion-exchange protein from the genome of the basidiomycete Phanerochaete chrysosporium (PcAEP). PcAEP is a 618-amino acid protein that is homologous to the human ...

We hypothesized that the function of duodenocyte apical membrane acid-base transporters are essential for H(+) absorption from the lumen. We thus examined the effect of inhibition of Na(+)/H(+) exchanger-3 (NHE3), cystic fibrosis transmembrane regulator (CFTR), or apical anion exchangers on transmucosal CO(2) diffusion and HCO(3)(-) ...

Copper is an essential micronutrient in humans and is required for a wide range of physiological processes, including neurotransmitter biosynthesis, oxidative metabolism, protection against reactive oxygen species, and angiogenesis. The first step in the acquisition of dietary copper is absorption from the intestinal lumen. The major human high-affinity copper uptake protein, ...

Marine teleost fish osmoregulation involves seawater ingestion and intestinal fluid absorption. Solute coupled fluid absorption by the marine teleost fish intestine has long been believed to be the product of Na(+) and Cl(-) absorption via the Na(+) :K(+) :2Cl(-) co-transporter (NKCC2). However, the past decade has revealed that ...

The anion exchange behavior of thorium in sulfuric acid solution and the separation of lanthanum from thorium by anion exchange were investigated. (C.H.)

The parallel effects of the anion transport inhibitor DIDS (4,4'-diisothiocyanostilbene-2,2'disulfonate) on net chloride flow and on chloride exchange suggest that a major portion of net chloride flow takes place through the anion exchange system. The ''slippage'' model postulates ...
