Abstract

In the present work, lead(II) at trace level was extracted by a dispersive liquid-liquid microextraction procedure. The process was followed by flame atomic absorption spectrometry (FAAS) for trace determination of lead. Tropaeolin OOO was used as the chelating agent for lead(II). The analytical conditions for the quantitative recoveries of lead(II) were investigated. Lead (II) - Tropaeolin OOO chelate was quantitatively extracted to 200 μL of CCl4 at pH 4. The limit of detection (LOD) was 11.4 μg L -1 . The recovery tests from the certified reference materials TMDA 64.2 and TMDA 53.3 Water Samples were in good agreement. The microextraction procedure showed applicability to wastewater and hair samples obtained from Kayseri, Turkey.
