Analysis of Low Lead and Cadmium Concentrations in Soil Extracts by Graphite Furnace Atomic Absorption Spectrophotometry
An analytical procedure was derived to provide an accurate measurement of low lead (Pb) and cadmium (Cd) concentrations in soil extracts using graphite furnace atomic absorption spectrometry (GFAAS). Based on peak area measurements and with background correction, the use of 2% phosphoric acid as...

| description |
An analytical procedure was derived to provide an accurate measurement of
low lead (Pb) and cadmium (Cd) concentrations in soil extracts using graphite
furnace atomic absorption spectrometry (GFAAS). Based on peak area measurements
and with background correction, the use of 2% phosphoric acid as
chemical modifier enables the GFAAS to give measurements of Pb and Cd
concentration as low as 3 fLg dm-3 with a high degree of precision. The modifier
ensures a single well-defined atomization peak of the analyte, and therefore
higher sensitivity and accuracy in the measurements. |
