Protein chromatography on an anion-exchange resin

Archives of Biochemistry and Biophysics, 1956
Abstract 1. 1. A technique for protein chromatography on the anion-exchange resin Dowex 2 is described. 2. 2. The stepwise elution of human serum albumin has been studied in some detail. 3. 3. A displacement technique has been used for the separation of the alkaline and acid phosphatases in human cancer serum. 4. 4.

On anion-exchange resin selectivities

Journal of Inorganic and Nuclear Chemistry, 1962
Abstract The selectivity of anion-exchange resins in contact with very dilute external solutions (negligible resin invasion by non-exchange electrolyte) is considered due in large part to changes in the solvation of the ions, resulting from differences in the properties of the resin-phase solution and the external dilute aqueous solution.

Exchange equilibria on anion resins

Desalination, 1974
Abstract Selectivity coefficients, free exchange energies and enthalpies between 5°C and 45°C of different anion resins with functional groups of the amino type were determined for the SO−4/Cl− system in a range of bulk salinities lying between 6 x 10−3 and 2.4 N The experimental results showed that the selectivity for the bivalent ion depends ...

Chloride-sulphate exchange on anion-exchange resins

Journal of Chromatography A, 1974
Abstract The exchange rates for the complete conversion of many anion-exchange resins from the chloride to the sulphate form when particle diffusion is the controlling mechanism have been measured. Infinite solution volume conditions were adopted, using the centrifugal stirrer-reactor technique.

Some ion-exchange resins for anion-chromatography

Talanta, 1987
The quaternary ammonium salts, n-butyltrimethylammonium iodide, 1,1,3,3-tetramethylbutyltrimethylammonium iodide, n-octadecyltrimethylammonium iodide and tri-n-dodecylmethylammonium iodide were synthesized from commercially available amines and together with n-hexadecyltrimethylammonium bromide tested for retention by a series of macroreticular resins (

Isoporous Anion-–Exchange Resins

2011
Publisher Summary This chapter provides a brief overview of isoporous anion-exchange resins. Styrene–divinylbenzene (DVB) copolymers show a remarkable advantageous property; they can readily enter into many chemical transformations. They have significant role in the synthesis of various catalysts, polymeric reagents, chromatographic separating media,
