Procedure to reduce sulphite in wine with anion-exchange resin

Acta 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.

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 ...

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

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

Soil 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)

Geochemical 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

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

, 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.

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

, 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).
