Özet

In this study, the concentrations of 24 elements, which are suspicious to be found in drinking and utility waters for the province of Antalya/Turkey, were determined using an inductively coupled plasma-mass spectrometer (ICP-MS). Validated methods with a low limit of detection are required to analyze such waters. The method was validated considering selectivity, limits of detection and quantification, sensitivity, linearity, operating range, accuracy, precision, and measurement uncertainty. All monitored isotope calibration plots had a correlation coefficient of 0.9994 or higher. According to the results of recovery, the expected results of all element isotopes were determined in the range of 94–104%. The average precision quantities for items were calculated as percent relative standard deviation (%RSD) between 0.10 and 2.31%. The analytical method provided here for detecting the concentrations of 24 elements in drinking water samples with demonstrated traceability and estimated uncertainty can yield reliable and internationally comparable results.
