دراسة بعض العناصر الثقيلة و ظاهرة الكلورة في تربة ملوثة بالمخلفات النفطية

Abstract EN

This study was conducted to investigate the effect of the oil waste in raisers phenomenon of chlorination and its role in heavy elements in the soil of Samawah oil refinery.

After preliminary laboratory procedures, test results showed increase the amount of heavy elements such as lead, nickel and cadmium in the soil pedonsthat affected by oil residues compared to non-affected soil pedon.

As a result of drought and perhaps the role of the disability caused by aromatic and aliphatic compounds to the petroleum residue that gets geometrical arrangement and the process of crystallization of magnesium hydroxide within the inner layers of Clay minerals (1:2) expanding Montmorillonit and Vermiculite by transforming them into metal chlorite because of the Brucite layerdeposition and the occurrence of chlorinationphenomenon.

This was confirmed the result of X-ray diffraction existence bloated chlorite on site which consists of Montmorillonit or Vermiculitemetals when affected pedons soil horizons in the waste oil, without his presence in the comparable soil of Pedon which was in similar environmental conditions to those pedons soil accept of the wastessoil
