Fourier Dönüşümlü Kızılötesi (FTIR) Spektroskopisinin Killerin Analizlerinde Kullanılması

Öz

Bu makale, killerin yüzey karakterizasyonu için Fourier Dönüşümlü Kızılötesi (FTIR) Spektroskopisi uygulamasının bir çalışmasıdır. Killerin su arıtma, yağ adsorpsiyonu gibi yüzey işlemlerinde ya da yardımcı maddelerde ve ilaçlarda aktif olarak kullanımı son yıllarda büyük ölçüde artmıştır. Killerin yüzeyinde bulunan hidroksil grupları, su molekülleri ile kolayca bağlayabilmektedir. Bu hidroksil gruplar organik gruplarla reaksiyona girerler ve onların kızıl ötesi bölgedeki titreşimleriyle tespit edilebilirler. Bu nedenle FTIR, killerin yüzey karakterizasyonunda kolayca kullanılabilen teknik bir yöntemdir. Bu makalede, temel kil minerali numuneleri (bentonit, sepiyolit, kaolin ve perlit) incelendi ve kimyasal bileşimlerinin büyük miktarda alüminyum oksit ve silisyum oksit içerdiği gözlendi.

Application of Fourier Transform Infrared (FTIR) Spectroscopy to Analysis of Clays

Öz

The present paper should be considered as a study of the application of Fourier Transform Infrared (FTIR) Spectroscopy for surface clay characterization. The application of surface clay materials for water treatment, oil adsorption, excipients or as active using in drugs has largely increased these recent years. The surface clay material presents hydroxyl groups, which can link very easily water molecules. These hydroxyl groups can react with organic groups and by their vibration in the infra-red region, FTIR can be easily used as a technical method for surface clay characterization. In this paper, the basic clay mineral specimens (bentonite, sepiolite, kaolinite and perlite) were examined and shows the chemical compositions of the clay where alumina oxide and silica oxide are present in major quantity.
