Investigation and Development of Polarographic Method for Pb (II) and Cd (II) Analyses in Oils

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