Abstract

A fast method for preconcentration and separation of lead in nanogram quantities from fresh drinking waters (source, well, tap) and waters for irrigation using coflotation is described. Cobalt(III) hepthyldithiocarbamate, Co(HpDTC)3, is applied as a collector. The experimental conditions for a successful remove of analyte are optimized. After flotation separation from the mother liquor, the solid sublate containing trace of Pb was dissolved and the determination was performed by Zeeman electrothermal atomic absorption spectrometry (ZETAAS). The ZETAAS limit of detection for Pb is 0.274 g/l.
