This paper provides a method for directly determining vanadium in workplace air by direct current plasma atomic emission spectrometry (DCP-AES). Wavelength selection, instrument operating parameters, and sample preparation methods were studied. It was found that the most suitable wavelength for the analytical line is 437.924 nm (DL 0.006 mg/L) but also the line 309.311 nm (DL 0.003 mg/L) can be used. The results obtained by DCP-AES were compared with those obtained by both flame (FAAS) and electrothermal atomization (ETA-AAS) atomic absorption spectrometry.
