Characterization of Philippine natural bentonite
Bentonite is mainly composed of montmorillonite (Uddin, 2008) and other minor nonclay minerals, in which it has an overall negative charge either in tetrahedral sheet or octahedral sheet form. Montmorillonite, a smectite clay mineral composed of three layers, has a 2:1 ratio of Si4þ tetrahedral to Al3þ octahedral sheets.
