Lead preconcentration onto C-18 minicolumn in continuous flow and its determination in biological and vegetable samples by flame atomic absorption spectrometry

A procedure for the preconcentration and determination of lead in vegetable and biological samples was developed in the continuous mode coupled to a flame atomic absorption spectrometer. Lead is quantitatively preconcentrated in acetic buffer as its diethyldithiocarbamate chelate onto a C-18 minicol...
