Analysis of mineral drug montmorillonite by IR spectra / 中草药

ABSTRACT

Object In pursuit of a clear cut view on the change of water molecules in the crystal lattice of montmorillonite, to provide a basis for the study of mechanism of action and its further development Methods The chemical structure of the mineral was studied by IR spectral analysis Results Information concerning the change of water in regard to its chemical structure were obtained Conclusion Montmori llonite is a mineral clay which can expand to exhibit its absorption properties, and can be used as an active absorbent excipient in drug formulation
