HUANCA Z, Paul K et al. Study of the hydrotermal modification of an Ignimbritic mineral to obtain synthetic zeolite of high capacity of cationic exchange . Rev. Bol. Quim [online]. 2019, vol.36, n.4, pp.173-179. ISSN 0250-5460.

Abstract This research led to the establishment of a methodology for the morphological characterization of an ignimbritic mineral. The material was collected in the area of Uchumayo, Peru. The samples were analyzed by scanning electron microscopy (SEM). The synthetic zeolite type NaP1 was obtained by hydrothermal activation in an alkaline medium of NaOH from ignimbrite. The morphology of the mineral was determined before and after the activation process. In addition, the cation exchange capacity of the material by method 9081 (cation exchange capacity of residues) was determined by atomic absorption spectroscopy. It is concluded that from the ignimbrite mineral, synthetic zeolite type NaP1 was obtained. On the other hand, a high cation exchange capacity was manifested, thus defining an important alternative for the region in the remediation and mitigation of heavy metal pollution in industrial effluents through ion exchange processes.
