Abstract

The extraction of the chemical species Cr, Ni, Cu, Zn, Cd, and Pb from a sewage sludge-treated soil with various extractants (ammonium acetate, acetic acid and EDTA) has been studied by using two analytical techniques: inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). A comparison of the mean values measured by the two techniques with the t-criterion reveal that the differences are not significant in all the extractants mentioned above. Results are also compared to data from a laboratory intercomparison exercise organised by BCR. A fast screening of the concentration of other trace metals could be provided by ICP-MS with good precision and low detection limits.
