FT-IR Spectroscopy Investigation of Soils From Yelagiri Hills, Tamil Nadu, India

FT-IR spectroscopy is apowerful tol for asesing the mineralogical compositon of the soils. In the present study an atempt has ben made to investigate soils of Yelagir Hils, Tamilnadu India by Fourier transform infrared (FT-IR) spectroscopy. Qualitative analyses were caried out to determine the major and minor constiuent minerals present in the samples from the band positon or location of the peaks. From the prominent IR absorption peaks, the minerals identifed with the available literature are quartz, microcline, orthoclase, kaolinite, montmorilonite, ilite, and organic arbon. XRD confirms the presence of these minerals in soils. The interpretation of results is made from the characteristics of IR absorption bands. The results how that he FT-IR technique is apotential tol for the characterization of soil minerals.
