Abstract
Raw montmorillonites treated with mixed Al-Fe pillaring solutions, wit h Fe/(Al + Fe) molar ratio between 0.1 and 1, and heated at 300 degree s C lead to large d-spacings according to XRD which increase from 52 A ngstrom for the sample with the lowest iron content to 76 Angstrom for the pure Fe-treated clay sample.
