Natural Microporous Materials in Environmental Technology

The material included in this volume contains both fundamental aspects as well as novel applications of natural microporous materials. It is divided into thematic units. The first section deals with novel potential applications of clays and chemically modified forms in environmental technology. The second and third sections relate the utilisation of natural zeolites and naturally occurring oxides, hydroxides and oxyhydroxides (a group of natural microporous materials with promising physicochemical properties that has not yet been completely investigated). The fourth section includes material that could not be classified in the other three.
