摘要：
The interfering effects of various foreign ions in the determination of mercury were studied by cold vapour atomic absorption spectrometry. There were serious depressing interferences from Ag, Au, Pt, Pd, Rh, Ru, Cu, Co, Ni and Pb. However, by using cyanide as a complexing agent these interferences could be completely eliminated over a wide range of interferent concentrations.
