Szilard-Chalmers Reaction of Anionic Cobalt Complex Ions on Ion-Exchange Resins

Isolation of Uranium by Anionic Exchange Resins

A separation methodology to isolate natural uranium from its radioactive daughters: Th, Ra, Bi, Pb, Pa and Po, was developed using an only one anion exchange resin and varying concentrations of HCl solutions. Three types of anion exchange resins were tested and the separation process was followed by gamma and alpha spectrometry. Uranium can be quantitatively isolated from its descendants using ...

[Ion exchange resins].

Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...

Displacement Chromatography on Synthetic Ion - exchange Resins

In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...

XAFS Study of Thermal Effect on Hydration Structures of Inorganic Ions in Ion- Exchange Resins

Dimerisation of Isobutene on Acidic Ion-exchange Resins

Dimerisation of isobutene produces diisobutenes that can be hydrogenated to isooctane (2,2,4-trimethyl pentane). Isooctane can be used as a high octane gasoline component. The aim of this work was to study the selective production of diisobutenes through the dimerisation of isobutene on ion-exchange resin catalysts and to construct kinetic models for the reactions in the system for reactor desi...
