Use of ion exchange resins for tartrate wine stabilization
OENO One, 2006 The application of the cation exchange and double cation-anion exchange resins, regarding the wine tartrate stabilization, without previous treatment of wine by cold has been studied as well as their influence in phenolic, mineral and organic acid ...

Influence of the ionic composition on the diffusion mass transfer of saccharides through a cation-exchange membrane [PDF]
, 2013 Recent studies have pointed out that the presence of salts can change significantly the membrane process performances because of the resulting modification of the neutral solutes transfer through the membrane.

New Anion-Exchange Resins for Improved Separations of Nuclear Material [PDF]
, 2000 We are developing bifunctional anion-exchange resins that facilitate anion uptake by carefully controlling the structure of the anion receptor site. Our new ion-exchange resins interface the rapidly developing field of ion-specific chelating ligands with

New strategies for treatment and reuse of spent sulfidic caustic stream from petroleum industry
Química Nova, 2012 This work examines traditional and new routes for removal of H2S and other sulfur compounds from spent sufidic caustic (SSC). SH- (hydrogenosulfide) and S2- (sulfide) ions were quantitatively oxidized at 25 ºC using H2O2, NaOCl or a spent sulfochromic ...

Comparison of chromatographic ion-exchange resins VI. Weak anion-exchange resins [PDF]
, 2007 A comparative study on weak anion exchangers was performed to investigate the pH dependence, binding strength, particle size distribution, and static and dynamic capacity of the chromatographic resins. The resins tested included: DEAE Sepharose FF, Poros

Bioregeneration of sulfate-laden anion exchange resin
Water Research, 2022 Ion exchange technology removes ionic compounds from waters effectively but treatment of the spent regenerant is expensive. The bioregeneration of sulfate-laden strong base anion exchange resin was successfully tested using both pure and mixed sulfate-reducing bacterial cultures.

Anion Exchange Resins as a Source of Nitrosamines and Nitrosamine Precursors [PDF]
, 2016 Anion exchange resins are important tools for the removal of harmful anionic contaminants from drinking water, but their use has been linked to the presence of carcinogenic nitrosamines in treated drinking water.

Sorption of Pu(4) from nitric acid by bifunctional anion-exchange resins [PDF]
, 1999 Anion exchange is attractive for separating plutonium because the Pu(IV) nitrate complex is very strongly sorbed and few other metal ions form competing anionic nitrate complexes. The major disadvantage of this process has been the unusually slow rate at
