Abstract
Chemical analysis of soil samples collected from six different sites in Tarhuna region that has been investigated using flame emission spectroscopy, atomic absorption spectroscopy and UV/visible spectrophotometry techniques. The investigated elements includes: Sodium, Potassium, Calcium, Magnesium, Chromium, Iron, Copper, and Zinc. The eight elements was extracted by the acid digestion method. The obtained experimental results of chemical analysis indicate that the maximum concentration of the metals are more than 11835, 5258, 3355, 1565, 699, 27, 20.05, and 15.9 ppm for Ca, Fe, Mg, Na, K, Cr, Zn, and Cu respectively. PH value of the examined soil solutions is at the range of (8.64-9.11) and hence, all samples is alkaline. The total metal ion concentration (Σ Mn+) as nitrate/chloride for different sites was calculated and the maximum value was found at Al syed area. The elemental concentration can be arranged as Ca > Fe > Mg > Na > K > Zn > Cr > Cu.
