Preparation and Characterization of Natural Zeolite Modified with Iron Nanoparticles

Abstract EN

This study is aimed at investigating the structural and morphological characterization of natural and modified zeolite obtained from the state of Oaxaca (Mexico).

Iron nanoparticles were used for the zeolite modification.

The iron nanoparticles were loaded on the zeolite surface by homogeneous nucleation.

Adsorption kinetic models of pseudo first and second order were surveyed.

The characterization of pristine and modified zeolite was performed by Fourier transform infrared (FTIR), transmission electron microscopy (TEM), and X-ray diffraction (XRD).

From the results, three main phases were identified: clinoptilolite, mordenite, and feldspar.

We could also determine the adsorption capacity of the zeolites by means of adsorption kinetic models.
