Abstract
A method is developed for preparing of nanosized ion exchangers (nano ion exchangers, NIEX) as water-stable sols of a given ionic form of two types: nano cation exchangersand nano anion exchangers. According to their physicochemical properties, nano ion exchangers are simultaneously dissolved hypercharged ions and microscopic solid ion exchangers capable of solid-phase ion exchange. In chromatographic and other methods of analysis, can serve as modifiers of stationary and mobile phases, providing a high capacity of the first one and special buffer properties of the second one. Some results of using for the creation of polymodal phases for ion chromatography, as a modifier in capillary electrophoresis, and in a luminescence method for the determination of heavy metals (using copper as an example) in aqueous solutions are presented.
