Spectral study (FTIR, UV-Vis) of montmorillonite modified by ultrasound and potassium cations

This paper presented the spectral study (FTIR, UV-Vis) for samples of non-activated bentonite (calcium) which has in its composition a main mineral resource, montmorillonite (MMT). MMT, as a component which contains calcium ions (Ca-MMT, was modif...
