Zeolites and zeolite-based materials in analytical chemistry

Zeolites are inorganic materials with large surface areas and well-defined internal structures of uniform cages, cavities or channels. This review analyzes recent literature giving particular attention to applying zeolite and zeolite-based materials in developing approaches to electrochemical and optical sensing, and techniques for separation or preconcentration. We highlight the analytical potential of these materials and suggest avenues for further research. (C) 2005 Elsevier Ltd. All rights reserved.
