Özet
In this study, Differential Pulse Polarography (DPP) method was preferred of Cd (II) and Pb (II) levels,
which have toxic effects. This method was applied to determine Cd and Pb levels in cold-pressed olive
oil brought from 5 different provinces of Turkey. The samples were dissolved in microwave digestion
using concentrated HNO3 and H2O2. Analyses were carried out in acetate buffer (pH 4) to which EDTA
was added. The LOD for Cd and Pb was found as 0.74, 0.52 µg L-1
and the LOQ was 0.96, 0.82 µg L-1
.
Additions were made from standard Cd and Pb solutions and the % recovery values were measured as
98 and 99. The relative standard deviation (RSD, %) was found < 5. This method was found to be
sensitive to the analyses of two toxic elements in cold pressed olive oil
