Determination of Copper, Cobalt, Cadmium, Lead, Nickel and Chromium by Atomic Absorption Spectrometry in Bottled Minerals Water from Turkey after Preconcentration/Separation in Activated Carbon

Abstract

Copper, cobalt, cadmium, lead, nickel and chromium concentrations
were determined in some bottled mineral water samples purchased
from local markets in Nigde and Kayseri-Turkey by atomic
absorption spectrometry after preconcentration/separation procedure
on the activated carbon column as pyrocatechol violet complexes.
The concentration ranges of copper, cobalt, chromium, lead
and nickel were found to be as 10.3-37.4  μg/L, 2.0-2.3  μg/L,
2.0-4.6  μg/L, 2.0-3.4  μg/L 4.7-16.7  μg/L respectively. The cadmium
concentrations of all the samples were found to be below 0.1
 μg/L.
