HUANCA Z, Paul K et al. Obtaining of synthetic zeolite type NaP1 in alkaline medium from natural zeolite under laboratory conditions. Rev. Bol. Quim [online]. 2018, vol.35, n.2, pp.46-53. ISSN 0250-5460.

This research conducted to the establishment of a methodology for the morphological characterization of natural zeolite. The material was collected at the area of Lampa, Peru. The samples were analyzed by electron microscopy scanning (SEM). Synthetic zeolite type NaP1 was obtained by activation in a NaOH alkaline medium out of natural zeolite. Morphology of the ore was determined before and after the activation process. Also, the ability of cationic exchange of the zeolite material by the method 9081 (capacity of cationic exchange of waste) was determined by atomic absorption spectroscopy. The characterization of the material studied in terms of morphology before and after the activation process, and determination of the cationic exchange of the resulting material were achieved. It is concluded that natural zeolite was heulandite, from which synthetic zeolite type NaP1 was obtained. On the other hand, high capacity of cationic exchange was manifested defining thus an important alternative for the region in remediation and mitigation of pollution by heavy metals in industrial effluents through ion exchange processes.
