Acid Activation of Clay Minerals
P. Komadel,J. Madejová +1 more
TL;DR: Acid activation is a common chemical modification of clays, usually bentonites, with a hot solution of a mineral acid (typically HCl or H 2 SO 4 ), and it is used for both scientific and industrial purposes as discussed by the authors.

FTIR techniques in clay mineral studies
TL;DR: In this paper, the authors used FTIR techniques to distinguish between different types of clay minerals and to derive information concerning their structure, composition and structural changes upon chemical modification, and the selection of the sampling technique used depended on the purpose of the study and on the physical state of the sample.

Determination of crystallite size and lattice distortions through X-ray diffraction line profile analysis
TL;DR: In this paper, a detailed analysis of line profiles in terms of Fourier coefficients is presented, and the subsequent steps of measurement, data correction and evaluation are elucidated; alternatives are indicated; and it is expected that line profile analysis will become an automated routine-like analytical method soon, since the tools are available: non-expensive computers, error calculations and commercially available software.
