Remoción de Cu(II) Y Ni(II) en medio acuoso empleando zeolita cubana natural

Abstract

La adsorción es uno de los métodos para la eliminación de la contaminación en residuales líquidos, por ello las investigaciones científicas en la búsqueda de materiales no convencionales y de bajo costo, son de gran importancia. El objetivo de la investigación es caracterizar la remoción de los iones Cu(II) y Ni(II), empleando zeolita en estado natural de la zona central de Cuba, mediante el método de adsorción. Para lograr el objetivo se evaluaron las propiedades adsortivas del mineral y se determinaron los parámetros de adsorción de los iones Cu(II) y Ni(II). El estudio cinético demostró que el modelo de pseudosegundo orden describe la velocidad de adsorción de ambos contaminantes y la ecuación isoterma de adsorción de Freundlich es la de mejor ajuste para los iones Cu(II) y Ni(II). La capacidad máxima de adsorción de la zeolita natural fue de 22,148 y 90,09 mg/g respectivamente.
