Analysis for the Sorption Kinetics of Ag Nanoparticles on Natural Clinoptilolite

Abstract EN

The kinetic adsorption behavior of silver nanoparticles deposited on a natural zeolite from Oaxaca is presented.

Theoretical models as Lagergren first-order, pseudo-second-order, Elovich, and intraparticle diffusion were employed and compared with experimental data obtained by atomic absorption spectrophotometry technique.

Correlation factors R 2 of the order of 0.99 were observed.

Analysis by transmission electron microscopy revealed that the silver nanoparticles were homogeneously distributed on the zeolite.

Additionally, chemical characterization of the material was carried out through a dilution process with lithium metaborate.

An average value of 9.3 in the Si/Al ratio was observed and related to the kinetic adsorption behavior of the zeolite.
