The effect of alkali halide and nitrate salts on the emission intensit
y from Ag and Pb, excited using furnace atomization plasma excitation
spectrometry, has been studied. Compared with the emission signal obta
ined when there is no interferent, the presence of either NaNO3 or NaC
l as a comcomitant in the sample causes an interference effect by decr
easing the emission intensity over the power range 14-40 W.
