Determination of Ag, Cd, Pb, Zn and Pd in sea-water by thermal-ionization isotope-dilution mass spectrometry.
The concentrations of Ag, Cd, Pb, Zn and Pd in sea-water have been determined by thermal-ionization isotope-dilution mass spectrometry. The concentrations found, in ng/kg, were 0.6 +/- 0.4 Ag, 1.9 +/- 0.4 Cd, 18 +/- 8 Pb, 30 +/- 8 Zn and < 4 Pd. These levels are lower than some reported previously. Determination of Pd in sea-water is reported for the first time.
