We have carried out a theoretical and experimental study of pyrolysis curves for electrothermal atomic absorption spectral determination of a number of elements in the presence of metal-containing (Pd, Ni) modifiers in an activated carbon matrix. We have used thermodynamic modeling as the basis for establishing the conditions for a quantitative description of the thermochemical processes in a graphite furnace. The temperatures in the pyrolysis stage for the analyte elements and the patterns we see in the pyrolysis curves match very well.
