Recent advances in natural zeolite applications based on external surface interaction with cations and molecules
This review deals with recent research on natural zeolites, which is focused nowadays more on their external surface activity, than on their microporous character. External cation exchange capacity and ability to bind big organic molecules are conveniently exploited in sectors of environmental and health-care relevance. In fact, zeolites are able either to sequester harmful species from organisms and soils or to retain fertilizers and drug carriers for an effective slow-release to soils and organisms, respectively. In addition, their interaction with macromolecules, such as humic acids, leads to the formation of aggregates useful for soil remediation and reconstruction. The same products, or those obtained allowing cationic surfactants to bind on their external surface, display also interesting adsorption properties, valuable for soil and water decontamination.
