| Abstract | ||
| Abstract Natural Iraqi mineral clays , treated chemically and physically , have been doped with chromium oxides and investigated using powder X-ray diffraction , X-ray Fluorescence , thermal analysis , infrared spectra ,and technical instrumental analysis . Results indicate the presence of penta chromium oxide associated with chromium trioxide supported on clay minerals . The observed physical properties evaluated the scientific and economic utilization of those samples to be applied in solid phase extraction technique as adsorbents to separate Iraqi heavy crude oils into their simple components . Infrared and nuclear magnetic resonance spectra have been applied to study the chemical composition of the separated fractions . | ||
