| Sumario: | Due to their particular properties and potential applicability, nanomaterials have been studied in recent decades. The decrease in size to the order of nanometers modifies the optical (coloration, absorption, luminescence and emission), mechanical (ultra-hardening and anti-oxidation), thermal (heat exchange, melting point and thermal resistance), electrical (conductivity and insulation), magnetic (colossal magneto-resistance) and chemical properties of the materials. In the specific case of materials based on aluminosilicates, at the nanometric scale, they remarkably improve their properties by acquiring unique behaviors such as superplasticity, machinability, resistance, tenacity, and also the ability to be biocompatible and friendly to the environment. Among these materials we can mention nanotubes of aluminosilicates (imogolite, HOSiO3Al2(OH)3) and nanoparticles of leucite (KAlSi2O6), albita (NaAlSi3O8) and nepheline (NaAlSiO4), which in recent years have aroused special interest due to their applications. These nanomaterials have physical and chemical characteristics that give them great potential for their application as selective sorbents. The nanomaterials of aluminosilicates are presented as an alternative to the use of conventional materials since they offer a wide spectrum of particular properties which can be conveniently tuned depending on the application for the development of environmentally friendly extraction and separation methods, thus, they present a great potential in environmental applications. The objective of this plan is to develop new technologies based on hybrid nanometric materials for application in Environmental Chemistry. Different hybrid combinations of nanomaterials will be developed with organic, inorganic molecules and other nanomaterials in order to increase their sorption capacities. The implementation of nanomaterials based on aluminosilicates such as nanotubes and nanoparticles in solid phase extraction systems will be the basis for the removal of contaminants such as arsenic (As). Particular attention will be paid to the application of the methods developed for the treatment of water in contaminated areas of the province of Mendoza. |
