An automated solid phase extraction coupled with electrothermal atomic absorption spectrometric determination of Pb(II) in high salt content samples

► A new on-line system for separation and ETAAS determination of Pb(II) was achieved. ► The system was firstly designed and used in our instrumentation laboratory. ► The eluent mixing system was simple. ► Lewatit Monoplus TP207 chelating resin was firstly used for this purpose.
