摘要：

The behaviour of As, Bi, Cd, Pb, Se, Sb, Sn and Te as dithiocarbamate complexes in isobutyl methyl ketone (IBMK) was investigated using electrothermal atomic absorption spectrometry. Without chemical modification a pyrolysis temperature of 700-degrees-C can be used for Bi, 550-degrees-C for Cd, 800-degrees-C for Pb and 1100-degrees-C for Sb. Higher pyrolysis temperatures can be used for As, Se, Sn and Te by utilizing palladium or platinum as ion associate complexes soluble in IBMK. The influence of the furnace tube treatment and of the concentration of Pd or Pt on the pyrolysis and the atomization of the studied dithiocarbamate complexes is discussed.
