3.9. Comparison with other methods
Table 5 compares the characteristic data of the proposed method
with other preconcentration methods for determination of Au and
Ag in diverse samples that are reported in literature [1,14,21–31].
As it can be seen, they are mostly one-element methods, except
Refs. [25,29]. For both elements the recommended method possesses
wide linear dynamic range, low consumption of an organic solvent,
high sampling volume, high sensitivity and also lower detection
