INORGANIC INTERCALATION COMPLEXES OF HALLOYSITE:
AN INFRARED STUDY

NOPADOL CHAIKUM

Summary: The clay mineral "halloysite", which is a member of the kaolin family, exhibits an IR spectrum in the hydroxyl absorption region (4000-3000 cm^-1) similar to that for kaolinite. Certain features of the spectrum, however, depend on the amount of interlayer water present. It has been found that wnen the interlayer water is replaced by all ionic salt the spectrum is further modified by perturbation of the structural hydroxyl vibrations and by formation of hydrogen bonds between the intercalated meterial and the internal surfaces of the clay.
