Quantitative determination by atomic absorption spectrometry for macro elements of mineral waters from Romania

Abstract

In this paper there are presented the results of studies performed on characteristics of some existent mineral
waters, in three different regions of Romania (West Region, Centre Region and North Region). Regarding
this aim, the quantitative chemical analysis of macro elements: sodium (Na), potassium (K), calcium (Ca)
and magnesium (Mg) was performed, using a flame atomic absorption spectrometer VARIAN Spectr AA
110 type. In this case, the flame emission and absorption method was used. As a conclusion, for sodium the
maximum value recorded in mineral waters from the three regions taken into discussion, was obtained in
sample A1 (294 mg/L) in the west region, for potassium the maximum reached was 47.4 mg/L in sample B3
in the north region, for calcium the maximum value was recorded as 330 mg/L in sample A3 from north
region, and magnesium recorded the maximum value of 76 mg/L in sample B3 for north region. All samples
studied, are within normal limits established by law.
