Adaptación morfológica de una esmectita natural para evaluar la adsorción de amonio a partir de soluciones acuosas

Abstract

Abstract:In the present investigation, a clay originating in the city of Loja was modified with iron salts in order to improve the adsorption to the ammonium ion, which was also subjected to the process of modifying its structure to the form of pellets to obtain a new alternative to the conventional use that is the powder. It was evidenced that the modifications made are the necessary ones by means of a physical and chemical characterization. Now, the bibliographic review leads us to take into account that most of the clays studied conform to the Langmiur isothermal model, with this we conclude that ammonia is attracted to the specific sites of the adsorbent material, producing the chemisorption process. Also, in the same revision the vast majority of zeolites conformed to the pseudo second order kinetic model.
