An on-line system for enrichment and determination of lead (II) is presented. It is based on
the adsorption of lead (II) ions on a minicolumn packed with active carbon loaded with
Pyrogallol Red. After preconcentration step, the metal ions are eluted automatically by 5.0 ml
of 0.50 M nitric acid solution and the lead ion contents were determined by atomic
absorption spectrometry. The influence of chemicals, pH and flow variables were studied as
well as effect of potential interfering ions. Under the optimum conditions, the lead ions in ...
