Abstract EN
This study includes adsorption and desorption of Cadmium and lead and its relationship with soil polluted by used oils engines.
The experiment carried out using soil samples from ten different locations in addition to the soils treated with used engine oils.
Different concentrations of cadmium and lead were added in the levels of( 0, 1, 2 and 4) mmol L -1 with three replicates to achieve sorption and desorption process.
Langmuir and Freundlich equations were used to describe the sorption and desorption of cadmium and lead from soil samples.
Desorption index (DI), The study found That the amount adsorbed increases with increased of added Cd and Pb and variation of different soils chemical and physical properties study of the soils and the amount of calcium carbonate, organic matter, the quantity and quality of clay, pH and ionic strength and the Values of desorption Index (DI) gave a good indication for the detection of the potential risk of pollution of Cadmium and Lead in calcareous soils, which can be transmitted to the surface and groundwater as the desorption index (DI) was calculated for soils contaminated with different levels of used engine oil (0, 5, 10, 20%), Sulaymaniyah and Aldorah soils were treated with different concentrations of cadmium and lead (0, 1, 2, 4) mmol L-1.
It was observed that desorption Index increased with increasing the proportion of used engine oils.
Highest DI was recorded at 20% addition of oil for each of the soils
