A new amine based microextraction of lead (II) in real water samples using flame atomic absorption spectrometry.

A new amine based microextraction procedure has been established for the separation and preconcentration of lead (II). N , N -dimethyl-n-octylamine was used as extraction solvent and chelating agent for lead (II). Microsampling flame atomic absorption spectrometry was used for the determination of lead. The analytical parameters including pH, amounts of N , N -dimethyl-n-octylamine, sample volume etc. were optimized. The influences of the matrix components were also investigated. The validation of the procedure was done by the analysis of TMDA 64.2 certified reference material. The Limit of detection (LOD) of developed method was 2.6 μg L−1. The developed microextraction procedure was successfully applied to natural water samples. • A new amine based microextraction procedure has been established for the separation and preconcentration of lead. • N , N -dimethyl-n-octylamine was used as extraction solvent and chelating agent for lead. • The effects of analytical parameters were systematically investigated and optimized. • The method has been applied to the analysis of lead in water samples.
