Abstract |
The study was carried out in the laboratories of Deir-Ezzor research center to determine the content of Calcium Carbonate by Calsimeter and Volumetric methods in gypsiferous soils. Standard samples were prepared in the laboratory containing (10,20,30,40)% of Calcium Carbonate and (0,2,5,10,20,30)% pure gypsum. 30 samples of soil with different Carbonate Calcium content were collected from different areas of Deir Ezzor. Calcium Carbonate content was determined in all samples by the national standard methods (Calsimeter, Volumetric). The results showed that Calsimeter method is more accurate than volumetric method for the determination of Calcium Carbonate in gypsiferous soils. The average of total relative error in standard samples was (0.38%) in Calcimeter method. while it was (3.75%) in Volumetric method. The results also showed that as the gypsum content in the soil increased, the relative error in Volumetric method increased, and the difference among results between the two methods increased too. The percent of the difference between Calcimeter and Volumetric methods was (0.19%) when the content of gypsum in soil was 0.23%, and increased gradually with increasing the percentage of gypsum in the soil. The difference reached (72.58%) when the content of gypsum in tested soil samples was (0.75%).
Key words: Calcium Carbonate, Calcium Carbonate determination. |

أجريت دراسة في مختبرات مركز بحوث دير الزور، بهدف تقدير محتوى التربة من كربونات الكالسيوم بطريقتي الكالسيمتر والمعايرة في الترب الجبسية، حيث حضرت عينات قياسية تحتوي على كربونات كالسيوم نقية بنسبة (20,10، 30، 40،) %و(0، 2، 5، 10، 20 ، 30 )% جبس نقي، كما أخذت (30) عينة تربة ذات محتوى مختلف من كربونات الكالسيوم والجبس من مناطق مختلفة من دير الزور، وتم تقدير نسبة كربونات الكالسيوم في |
