Direct Air Capture Using Electrochemically Regenerated Anion Exchange Resins. [PDF]

open access: yesEnviron Sci Technol, 2022
Direct air capture (DAC) aims to remove CO2 directly from the atmosphere. In this study, we have demonstrated proof-of-concept of a DAC process combining CO2 adsorption in a packed bed of amine-functionalized anion exchange resins (AERs) with a pH swing ...

Adsorption of Anthocyanins by Cation and Anion Exchange Resins with Aromatic and Aliphatic Polymer Matrices. [PDF]

open access: yesInt J Mol Sci, 2020
This study examines the mechanisms of adsorption of anthocyanins from model aqueous solutions at pH values of 3, 6, and 9 by ion-exchange resins making the main component of heterogeneous ion-exchange membranes.

Procedure to reduce sulphite in wine with anion-exchange resin

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
The aim of this experiment was to eliminate SO2 ions present in wine using the anion-exchanger resins. To compare the effectiveness, 2 following strongly basic anion-exchange resin were used.

Novel Application of Hybrid Anion Exchange Resin for Phosphate Desorption Kinetics in Soils: Minimizing Re-Adsorption of Desorbed Ions

open access: yesSoil Systems, 2020
The process of phosphate desorption from soils is difficult to measure using stirred batch techniques because of the accumulation of desorbed ions in a bathing solution.

Evaluating ion exchange resin efficiency and oxidative capacity for the separation of uranium(IV) and uranium(VI)

open access: yesGeochemical Transactions, 2013
Background Previously described methods to separate dissolved U(IV) from dissolved U(VI) under acidic anoxic conditions prior to laboratory analysis were ineffective with materials currently available commercially. Three strong anion exchange resins were

Anion Exchange Resins as Sources of Nitrosamines and Nitrosamine Precursors [PDF]

open access: yes, 2012
Nitrosamines are a family of potent chemical carcinogens including, among others, N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), N-nitrosodi-n-propylamine (NDPA) and N-nitrosodi-n-butylamine (NDBA).

Influence of the ionic composition on the diffusion mass transfer of saccharides through a cation-exchange membrane [PDF]

open access: yes, 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.

Use of ion exchange resins for tartrate wine stabilization

open access: yesOENO 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 ...

Evaluation of anion exchange resins for processing plutonium--neptunium residues [PDF]

open access: yes, 1977
An anion exchange process was developed to process miscellaneous residues of plutonium plus 0.5 wt % neptunium to allow prompt return of the plutonium to a plutonium recovery process.

New Anion-Exchange Resins for Improved Separations of Nuclear Material [PDF]

open access: yes, 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
