Abstract

تمّ في هذا البحث تحديد بعض العناصر المعدنية الموجودة في التربة الزراعية, بطريقه  الصهر(Fusion Method)  المعتمدة على المزيج الصهور (Flux) تترا وميتا بورات الصوديوم كمادتين أساسيتين للحصول على عيّنات زجاجية متجانسة. استخدمت أطياف الفلورة لرونتجن (XRF) لتحليل كلّ من Ca، K، Fe وTi عند الخط . لم يتجاوز الانحراف المعياري النسبي المرتكب في تحديد (Fe) المـقدار 0.3 % والمقدار % 0.6 من أجل (Ti)، ولم يزيد عن 1 % بالنسبة لكلّّ من الكالسيوم والبوتاسيوم. كان حدّ الكشف عن الحديد 7.8´10-2 % وعن التيتانيوم 4.4´10-3 %، وبلغ القيمة 0.001 % من أجل الكالسيوم، والمقدار% 2.8 ´ 10-3 من أجل البوتاسيوم.

We have determined in this research the concentration of some trace mineral elements that are present in agricultural soil, by fusion method dependent on flux mixture (LiBO2 - Li2B4O7) as two basic materials for obtaining homogenous glass samples.(XRF) spectra have been used to analyse Fe, Ti, Ca, K, at the spectrum line .The relative standard deviation committed in determining (Fe) did not exceed the amount of 0.3%, and the amount o.6% for (Ti),and it did not go beyond the value 1 % in relation to both of calcium and potassium. The detection limit of (Fe) was 7.8 ´ 10-2 % and of titanium 4.4´10-3 % and it reached the value  0.001 % for calcium and the amount 2.8 ´ 10-3% for  potassium.
