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...
متن کاملClustering of divalent cation-vacancy pairs in alkali halide crystals
The analysis of experimental results of the clustering of divalent cation-vacancy pairs by Unger and Perlman is shown here to be unable to distinguish between their model of dimer formation and the earlier model of' Dryden for trimer formation under the conditions where it has been applied. In general, experimental results appear to correspond to overall third order kinetics in the pre-plateau ...
متن کاملPure silica gel as cation−exchange stationary phase in ion chromatography for mono− and divalent cations
Ion chromatography (IC) developed by Small et al . [1] is widely recognized as a simple, powerful and convenient analytical technique for the determination of various low−molecular−weight ionic compounds [2, 3]. Firstly, IC with conductimetric detection (IC−CD) was mainly applied for the determination of inorganic anions. This is because a lightly sulfonated styrene−divinylbenzene co−polymer (S...
متن کاملHighly Emissive Divalent-Ion-Doped Colloidal CsPb1–xMxBr3 Perovskite Nanocrystals through Cation Exchange
Colloidal CsPbX3 (X = Br, Cl, and I) perovskite nanocrystals (NCs) have emerged as promising phosphors and solar cell materials due to their remarkable optoelectronic properties. These properties can be tailored by not only controlling the size and shape of the NCs but also postsynthetic composition tuning through topotactic anion exchange. In contrast, property control by cation exchange is st...
متن کاملAlkali salt vapour deposition and in-line ion exchange on flat glass surfaces
Glassy materials provide a unique set of properties, such as transparency, high hardness and good chemical durability, forming ability, low cost production and the possibility of recycling. They are therefore used in a wide range of applications, e.g. windows, containers, displays, thermal insulation, optical lenses, data transport, or, e.g. as bioactive materials. The fact that glass is a rela...
