Quantitative determination by atomic absorption spectrometry for macro elements of mineral waters from Romania
Main Article Content
Absztrakt
The aim of this paper is to present the results of studies for some microelements from mineral water. Mineral
water was collected from three different regions of Romania (West Region, Centre Region and North Region).
The microelements: lead (Pb), nickel (Ni), manganium (Mn), iron (Fe), cooper (Cu), chromium (Cr), and
cadmium (Cd) were analyzed by atomic adsorption spectrometry determination, using the graphite tubular
electrothermic owen method VARIAN GTA 110. As a conclusion, the lead (Pb) maximum value recorded for
the west region waters was in sample A1 (18.6 µg/L), the nickel (Ni) exhibits maximum value in center region,
in sample C2 (54.15 µg/L), the manganium (Mn) reaches the maximum in the west region in sample A1 (360
µg/L), the iron (Fe) exhibits maximum value in sample B3 (6.25 µg/L) from north region, and for the cadmium
(Cd), the maximum value was reached in sample A1 (8.18 µg/L) from the west region. When comparing the
allowable limits for heavy metals, (ORDER NO. 975 OF 16 DECEMBER 1998 ON THE APPROVAL RULES OF THE
SANITARY HYGIENIC FOOD) were not observed exceedances of microelements concentrations studied.
