Chemical composition, physical properties and structural characterization of local natural mineral clays have been studied. The study approach is based on using X-ray diffraction and fluorescence, thermal gravimetric analysis, differential scanning calorimetry, infrared spectroscopy, instrumental and classical chemical analysis techniques. The results were compared with those obtained from acidically treated and chromium oxide doped clay samples. Four samples were prepared in order to be a more active and selective adsorbent materials. Soxhlet fractionating techniques were set for all the above types of adsorbents using four eluants gradually increased in polarity. The fractionation results showed significant variations in the fractions isolated according to their polarities as indicated by percentage results.
