Determination of some nutrientions (PO43-, NO3-, NO2-, NH4+) In the waters of the Dreikish dam
Abstract
The periodic analytical study of Dreikish dam water - Dreikish region - Syria was carried out by sampling water samples every two months in 2017-2018 for monitoring sites inside the lake area and for the water received from multiple sampling sites.
The study included the determination of some ions that feed the water of the Dreikish dam such as phosphate, nitrate, nitrite, and ammonium ions by UV/VIS spectroscopy.
The concentration of phosphate ions was ranged between (0.00-0.26) mg / l, with a percentage relative standard deviation not exceed than5.00%.
The concentration of nitrate ion was ranged between (0.3-12.0) mg / l, with a percentage relative standarddeviation of only 0.5%.
The concentration of nitrite ion was ranged between (0.01-0.71) mg / l, with a percentage relative standarddeviation of only 5.00%.
The concentration of Ammonium ion was ranged between (0.00-1.51) mg / l, with a percentage relative standarddeviation of only 5.00%.
Nitrite concentration was exceeded its permissible limit of drinking water at the dam site in the beginning of the summer of 2017.
Ammonium values were exceeded thepermissible limit of drinking water at the dump site in the ninth month and at the lake tail site in the seventh month of 2017.
