The proposed solvent assisted dispersive solid phase extraction
was successfully used for preconcentration of lead and cadmium
from different food and water samples. Determination was carried
out by a flame atomic absorption spectrometer. The SA-DSPE
allows the rapid extraction of cadmium and lead ions using a
low amount of sorbent material (0.02% (w/v%)). This method is
environment friendly and robust against very high contents of salt.
The other benefits of the method are its simplicity, ease of operation,
good accuracy and precision, short extraction time, low cost,
and a good enrichment factor. Although the obtained results in this
work are related to lead and cadmium determination, the system
could be readily applied for the determination of other metals
using various ligands.
