Abstract
The samples collected on 25 3 2012 from the University of Tikrit station and the Faculty of Pharmacy, University of Tikrit, and by 3 liters per sample. The study included some of the concentrations found for the elements Zn, Cu, Cd, Pb)) of the River Tigris and the results showed that concentration of Zn by the traffic station liquidation in the raw water is 2.3 mg/L at the wavelength 273 nm The concentration of Zn after passing station filter in the sample taken from the College of Pharmacy is 1.3 mg/L When wavelength of 273 nm , the element of copper before passing through the filter plant was the focus at 0.15 mg/L wavelength 241 nm and after the filter has fallen to 0.1mg/L at the wavelength 241 nm , the concentration of cadmium in raw water was> 0.5 mg/L at wavelength 251 nm and after passing the filter station became the focus> 0.05 mg/L at wavelength 251 nm, and that the concentration of lead in the raw sample> 0.1 mg/L at wavelength 251 nm and after filtering remained the focus> 0.1 mg/L at the same wavelength, and the results of a study of heavy metals (cadmium and lead) have shown the results of non-significant value for elemental copper and zinc.
