تحديد محتوي Sr و Ba و Ca و Fe و SO4-2 في المياه المرافقة للنفط الخام السوري

We have determined the content of certain chemical elements (Sr, Ba, Ca, and Fe) and SO4-2content within well water accompanying the Syrian crude oil in the fields of Al-Furat Petroleum Company. We have also studied the precipitation of these elements in the form of their sulfates. The results of determining the above mentioned elements using the atomic absorption technology gave quantitative contents which exceed the permitted level, leading to their falling as sulfate precipitates: CaSO4, FeSO4, BaSO4, SrSO4. Relative standard deviation committed in determining the concentrations of the above mentioned elements was within the error range of the technology used.
