PRIETO GARCIA, Julio Omar; CASTILLO GONZALEZ, Daimel; RODRIGUEZ CONTRERA, Elaine  e  MOLLINEDA TRUJILLO, Ángel. ADSORPTION OF URANYL IONS IN ASH OF SUGARCANE BAGASSE. cen. az. [online]. 2019, vol.46, n.2, pp. 11-20.  Epub 01-Jun-2019. ISSN 2223-4861.

The investigation aims a kinetic and thermodynamic study of uranyl ions adsorption in aqueous solution using sugarcane bagasse ash. From the kinetic point of view, it is a physical adsorption which support the pseudo-first order model where diffusive mechanism through the liquid film is fundamental. The models of Freundlich and Dubinin respond from the thermodynamic point of view to ions adsorption in aqueous solution.

Palavras-chave : adsorption; kinetics; thermodynamics; uranyl.
