摘要：

Investigations of signal enhancement in carbon-filament atomic absorption spectrometry are described. Several enhancements are shown to be due to preferential binding of the oxygen by the added interferent in the gas phase. This prevents the analyte atoms from reacting with the oxygen, thereby preserving or enhancing the atom concentration and thus the absorbance signal. © 1979.
