Crystal chemical and Ssructural characterization of natural and cation-exchanged mexican Erionite
In this work, the chemical structural characterization of the erionite-type zeolite from
Agua Prieta, Sonora, México, was performed on both pristine and Na, Ca, and Mg exchanged
samples in order to identify the various modifications due to cation exchange. The samples
investigated were those that showed the best behaviour of CO2 and CH4 adsorption at zero coverage
levels and the higher values of surface area reported in our previous studies. According to the
