| Summary: | In this study, ICP-OES was used to determine trace elements in Hirfanlı Dam Lake, which was established on Kızılırmak. Water samples were taken from polyethylene bottles from different parts of Hirfanlı Dam Lake by adding two milliliters of HCl. Trace elements in these examples were determined by Perkin Elmer ICP-OES device. Iron, copper, lead, cadmium, chromium, nicel, zinc, molybdenum and selenium elements in the water samples from the dam were determined with the ICP-OES device. Calibration of the elements at certain wavelengths was performed with suitable standard
solutions. The sensitivity of the elements in the certified sample was made by first measuring the device. Then, analysis of the elements in the water samples was made. According to the measurements nearest to the dam lake; Fe (III) 40 ± 0.3 µg / L, Cu (II) 10 ± 0.1 µg / L, Pb (II) 25
± 0.1 µg / L, Cd (II) 18 ± 0.1 µg / L Cr (III) 15 ± 0.2 µg / L, Ni (II) 12 ± 0.1 µg / L, Zn (II) 22 ±
0.2 µg / L, Mo (VI) 8 ± 0.1 µg / L Se (IV) was found as 35 ± 0.3 µg / L at 95% confidence interval and after 4 measurements.
