| Abstract Scope |
The characterization of a zeolitized tuff from the state of Guerrero, México was carried out using the techniques of XRD, XRF, FTIR, SEM-EDS, TGA, and DSC. The thermal stability, textural properties, and cation exchange capacity (CEC) were determined. The main minerals detected were zeolite from the heulandite series, with the presence of quartz, feldspar, and smaller proportions of micas. The surface area, micropore volume, and pore size were 16.33 m²/g, 0.005 cm³/g and 21.62 Å, respectively. The thermal stability is classified as heulandite due to the collapse of the structure starting at 300°C. The cation exchange capacity (CEC) was measured at 1.27 meq/g, with calcium (Ca²⁺) being the main exchangeable cation; therefore, the zeolite was a calcium-rich heulandite. |
