Synthetic Inorganic Ion-Exchange Materials. XXXXVI. Ion-Exchange Behavior of Titanium(IV) Antimonate Cation Exchanger for Alkali Metal Ions in Ammonium Nitrate Media

Bifunctional Polymer-Metal Nanocomposite Ion Exchange Materials

The unusual electrical, optical, magnetic, and chemical properties of metal colloids (better known in nowadays as metal nanoparticles, MNPs) have attracted increasing interest of scientists and technologists during the last decade. In fact, although Nanoscience and Nanotechnology are quite recent disciplines, there have already been a high number of publications that discuss these topics. [1-11...

V). Separation Processes-solvent Extraction/ Ion Exchange for Metal Ions

In the hydrometallurgical processing of complex ores/ concentrates/ secondaries/ wastes, the solutions containing different non-ferrous metals are obtained during teaching the materials in acidic, ammoniacal or alkaline lixiviants. The spent solutions and effluents are also generated in different process industries and contain metallic values. Their discharge in the sewage or river is major con...

Solid NMR Study of the Ion - Exchange Properties on ƒÁ - Titanium Phosphate with Alkali Metal Ions

Layered ƒÁ-titanium phosphate (ƒÁ-TiP), Ti(HP04)2.2H20, is well known as the host material of intercalation compounds and the inorganic ion-exchanger of H+/metal ion system. It was found to have high ion-exchange selectivity for Rb+ and Cs+ among alkali metal ions. The ionexchange reactions for these ions progressed in two steps according to pH. Part of water molecules in the mterlayer of ƒÁ-Ti...

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...
