Análisis bibliográfico de tipos de isotermas de adsorción Freundlich, Langmuir y Brunauer, Emmett, Teller en zeolita para la recuperación de suelos agrícolas de la provincia de Cotopaxi en el periodo 2020.

In the province of Cotopaxi in recent years has established some production systems for their products, which has shown a more rapid wear of the soil, reducing the quality of production of them. At present, it has been proven that the progressive accumulation of MTE (trace metal elements) in soils can generate negative effects on human health, since the consumption of these heavy metals interferes with enzymatic processes, which can generate different pathologies such as intoxication. For this reason, in the present project, the bibliographic analysis of types of adsorption isotherms was established, considering three types of methodologies: Freundlich, Langmuir, and Brunauer, Emmett, Teller (BET), with the purpose of establishing which is the most feasible for adsorption in Zeolite as an alternative for the recovery of agricultural soils in the province of Cotopaxi. For its development, it was based on bibliographic information sources, and it was also used research techniques and instruments to carry out the methodological analysis of adsorption isotherms; for the validation of the scientific question, the bibliographic guide was elaborated. As a result of the analysis of adsorption isotherms, it was evidenced that Freundlich's isotherm does not have a scientific validation that supports its results, while Langmuir's isotherm, its adsorption system is established in monolayer and it is used more for chemisorption, allowing to conclude that the best isotherm is BET's since its adsorption is in multilayer and that allows a more efficient adsorption. We can conclude that the objectives set out in this research project have been completely fulfilled and we can establish that zeolite adsorption for the recovery of agricultural soils in the province of Cotopaxi is feasible.
