Ion Exchange and the Swelling of Ion-exchange Resins
Russian Chemical Reviews, 1969The review deals with the modern hypotheses concerning the physicochemical properties of ion-exchange resins and their effects in the interaction between resins and solvents and solutes, mainly electrolytes. The problems associated with the permeability of resins, the steric accessibility of the functional centres, and their screening are discussed ...

Ion-exchange chromatography is a versatile method of separation and concentration which is applicable to many kinds of analysis, inorganic, organic, and biochemical. The experimental technique is simple and in most cases fairly rapid. In the great majority of inorganic applications, all that is needed is a tube about 25 cm long and 1 cm i.d ...

Ion-Exchange Selectivities of Inorganic Ion Exchangers
2021The most important groups of inorganic ion exchangers are clays, zeolites, hydrous oxides, insoluble acid salts, heteropolyacids, and hexacyanoferrates. Some of these inorganic ion exchangers exhibit especially high selectivities for certain elements or groups of elements.

ION-EXCHANGE STUDIES WITH SOME COMPLEX IONS ON ION-EXCHANGE RESINS
Solvent Extraction and Ion Exchange, 1993Abstract The ion exchange equilibria of Cr(NH3)3+, Cr(NH3)5Cl2+, cis-Cr(en)2Cl2 +, trans-Cr(en)2(SCN)2 +, Cr(H2O)6 3+ complex ions against La3+ ions were studied. The effect of the ionic charge, radius and composition of various chromium complex ions on the selectivity were discussed. The logarithms of the selectivity constants were plotted versus mole

The properties and preparation procedures of ion-exchange membranes are closely related to those of ion-exchange resins. As with resins, many types of membranes are possible with different polymer matrixes and different functional groups to confer ion-exchange properties on the product.

Microporous and Mesoporous Materials, 1998
Publisher Summary This chapter explains the ion exchange capacity in zeolites. In a traditional aluminosilicate zeolite the source of the ion exchange capacity is the extent of isomorphous substitution of Al for Si in the tetrahedral framework. The theoretical exchange capacity thus can be derived from the elemental composition.

Analytica Chimica Acta, 1967
Abstract A review is given of variables which affect the separation factors in ion-exchange chromatography. In favorable cases the influence of complex formation, pH, and eluant concentration can be predicted by simple calculations, whereas the interaction forces inside the resin phase are still largely unexplored.
