Аннотация
Data on the methodology of sorption preconcentration are surveyed and the key concepts and quantitative parameters are given. The approaches to the preconcentration are considered, and various sorbents are characterised. Examples of using cellulose, styrene–divinylbenzene sorbents with grafted complexing groups, polyurethane foams and non-covalently modified silica gels, including those prepared by the sol–gel strategy, for preconcentration of inorganic and organic substances and development of combined and hybrid methods of analysis are given.
