The results showed that volcanic materials share certain elements in common, and due to the presence of oxygen, they are forming metal oxides of Si, Al, Fe, Ca, K with different concentrations. The main metallic oxides are Si and Al, the one with the highest concentration is Chimborazo (55.70% SiO2 - 17.40% Al2O3), followed by Tungurahua (51.20% SiO2 - 19.80% Al2O3), The Altar (48.60% SiO2 - 11.76% Al2O3) and the Reventador (38.10% SiO2 - 13.40% Al2O3, being the main mineralogical phases: Andesine, Quartz, and Anortoclase for the Chimborazo volcano, the Tungurahua by Albite, Anortite and Anortoclase, The Reventador by Albite, Anortoclase and Anortite and The Altar by Albite, Wuesite, and Anortoclase. The presence of different amphoteric metal oxides indicates the alternative of using these igneous materials in natural and wastewater treatment, thanks to their ion exchange and adsorption characteristics and properties. |
