- ADSORPTION KINETICS OF N2O ON NATURAL ZEOLITES ROSARIO HERNÁNDEZ HUESCA JESÚS PÉREZ ARCOS DIANA VARGAS HERNÁNDEZ MARÍA ANA PÉREZ CRUZ Ciencias de la Tierra Erionite Mordenite Clinoptilolite Adsorption rate The adsorption kinetics of pure N2O on natural zeolites of the erionite (ZAPS), mordenite (ZNT), and clinoptilolite (ZSL) types has been measured in the temperature range of 0-100 ºC using a glass, high-vacuum volumetric system. The adsorption capacities of N2O on the ZNT and ZSL samples were lower than that on ZAPS. This result can be due to the limiting volume of the micropores of these zeolites and to the quantity of cations available per unit mass of the dehydrated zeolites (cationic density). It was found that the adsorbed amount and the adsorption rate diminish with increasing temperature. This behavior allows us to deduce that the adsorption process of N2O is not of the activated type and that it is not influenced by kinetic effects. It was established that the adsorption of N2O on ZAPS can be effected most efficiently at ambient temperature, whereas the use of ZSL could be recommended at 100 ºC. 2016 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37045328009 https://www.redalyc.org/journal/370/37045328009/ https://www.redalyc.org/journal/370/37045328009/html/ https://www.redalyc.org/journal/370/37045328009/37045328009.epub https://www.redalyc.org/journal/370/37045328009/movil en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.2 Vol.32
