Abstract
The study of IR spectra in the range of 400 to 1700 cm(-1) of cation e xchanged natural clinoptilolite-heulandite samples has shown the influ ence of the characteristics of cations and their content in the freque ncy and transmittance of vibration modes of zeolite. The 450 cm(-1) ba nd assigned to T-O internal bending, 1205 cm(-1) band of T-O internal asymmetric stretching, and 1640 cm(-1) band of OH bending, were most a ffected by the cation exchange and thermal history of the sample.
