Trace Lead Measurement and Online Removal of Matrix Interference in Geosamples by Ion-Exchange Coupled with Flow Injection and Hydride Generation Atomic Fluorescence Spectrometry
A flow injection method has been developed for the direct determination of free available Pb(II). The method is based on the chemical sorption of Pb(II), from pH7 solutions, on a column packed of chelating resin. The retained complex was afterwards eluted with hydrochloric acid followed by hydride g...
